Parking & Trailhead Information for Lost Lake Hike

Parking is very limited at the Hessie Trailhead, so be sure to take some time to review these details before departing for your hike. Because the Hessie trailhead is one of the most popular in the state, Boulder County offers a shuttle that runs from Nederland every 15-20 minutes on weekends during the Summer months and on some holidays. For full details on the Hessie Trailhead Shuttle, please see the Boulder County page for the shuttle service. This shuttle departs from the RTD Park-n-Ride in Nederland.

Directions to Hessie Trailhead

At the roundabout in Nederland, Colorado, drive south onto CO-119/South Bridge St. Take a right onto Eldora Road which will take you to Elodora Colorado. The road continues through Eldora, and changes to Eldorado Road. It proceeds out of town and changes its name to Hessie Road. About 3/4 of a mile outside of Eldora, the road will split, 4th of July Road goes to the right, and Hessie will turn to the left. The 2WD Hessie Trailhead Parking area is at this split. Do not park alongside the road, as you will likely be fined. If the parking area is full, then go back to Nederland for the shuttle (weekends and holidays). There is parking for 4WD vehicles further up the dirt road and closer to the beginning of the official trail. It's important to know that rains can quickly flood this segment of Hessie Road.

The Hike: Lost Lake Trail

If taking the shuttle, it will drop you off at the 2WD parking area. From here, hikers will follow a trail for that runs along the north side of the 4WD dirt road. The trail runs past a small pond and will keep to the right-side of the 4WD Hessie Trailhead road until it arrives at the official trailhead. Keep your eyes peeled for Moose who frequent these waterlogged meadows along this lowland segment of the trail. At approximately 1/2 mile from the shuttle drop, a sign marks the site of the old mining town of Hessie, Colorado.

Soon, the trail will cross the North Fork of Middle Boulder Creek via a footbridge and a large sign will map and describe the several trails and destinations that can be accessed from this point. Hikers will continue on this old mining road as it leads uphill towards both Lost Lake and the intersection for the trails that lead to Devil's Thumb Lake, Jasper Lake, Woodland Lake, King Lake, and Bob and Betty Lakes. This trail profile will describe the route to Lost Lake only.

The next 1.2 miles climbs by way of switchbacks over rocky and steep terrain. Wildflowers pepper the trailsides and the riparian zone along Middle Boulder Creek. At the first trail intersection (Devils Thumb and Devils Thumb Bypass Trails), a sign will mark the way to Lost Lake and give distances and point the direction to the other destinations. Here the trail to Lost Lake will go left and cross another footbridge. Soon, a waterfall and set of cascades will come into view. The trail will make its way to a second intersection and sign. Here, the trail for Lost Lake departs, once again, to the left.

From this point, Lost Lake is just 1/2 mile away. It's a steep segment but worth the views when you arrive. At Lost Lake, hikers can explore the outside circuit of its shores (this will add both time and distance to the hike). Return via the same trails for a total of 4 miles.

Shanahan Ridge Hike Near Boulder

The Shanahan Ridge Loop Hike is an easy, 4-mile lollipop-loop trail with stunning views of the Shanahan Ridge of the Flatirons in Boulder, Colorado. Explore the full Shanahan Ridge Loop hike profile below for trail map, driving directions, and more tips and details to help you enjoy this hike in Boulder.

Trail Snapshot: Shanahan Ridge Loop Trail in Boulder, Colorado

Parking & Trailhead Information for Shanahan Ridge Loop Trail

The Shanahan Ridge Trailhead is located just along Lehigh Street south of Boulder. From US 36, follow Table Mesa Drive West to its intersection with CO 93. Turn left onto 93 and follow it for less than a mile. Turn right onto Greenbriar Boulevard which eventually becomes Lehigh Street. The trailhead is on the left/southwest side of the road and marked by a trail post and trash receptacle. There is actually no parking lot because the trailhead is located in a residential area. Because of this please exercise extra care and respect for the residents as you park along Lehigh or adjacent streets. Be aware of city parking signage.

The Hike: Shanahan Ridge Loop Trail

The Shanahan Ridge loop is best hiked clockwise in order to gain the best views of the Flatirons and surrounding countryside. Going left on the first junction will take you onto a connector trail that will next intersect with the South Fork Shanahan Trail. This trail begins with a gradual ascent which becomes more demanding. If you are acclimatized to the altitude and hike a fair amount, you'll find this segment easy; but beginner hikers and those of us who are not in the best of shape will find this a moderately demanding trail.

Continue on the South Fork Shanahan Trail for about 1.8 miles as it weaves through ponderosa forest and opens out to captivating vistas of the Flatirons. The trail will terminate at a junction with the Mesa Trail. Follow this trail North (right) as it winds along the base of the Shanahan Ridge of the Flatirons.

After approximately a 1/2 mile on the Mesa trail, it will intersect with the North Fork Shanahan Trail. Taking a right onto the North Fork Shanahan leads backdownhill for about 1.3 miles to the trailhead.

Parking & Trailhead Information for St. Vrain Mountain

From Denver, take Interstate 25 to either 36 or 66 to Lyons. In Lyons, follow 7 to Allenspark. In Allenspark, turn left onto Ski Road - FR-107. This will be marked with a street sign and a home-crafted sign made out of an old pair of skis. Follow this dirt road as is weaves through Allenspark then a series of dispersed cabins for about 2 miles until the road terminates at the trailhead. There is parking for only about 8 vehicles at the trailhead. There is additional parking along the road, but make sure that you're not blocking cabin drives or tearing up the roadside. You may have to park a ways back down the road if crowded. I hiked this on the weekend and the lot was full around 8 AM. There are not restrooms or potable water at the trailhead.

The Hike: St. Vrain Mountain Trail

The hike begins in the shade of aspen, spruce, and lodgepole pine forest. This first segment is easy and gradual, getting steeper as the sounds of distant St. Vrain Creek grow louder and closer. Wildflowers become more prevalent and soon the trail begins to follow right alongside the course of the creek.

Then the switchbacks begin. I hiked this in late-May after a Winter when our snowpack was below normal. So it was snow-free until around mile 2. From about mile 2 to mile 3, intermittent snow covered about 3/4 of the trail. I didn't bring snowshoes but had it been early May, I definitely would have needed a pair. Trekking poles were essential for negotiating the trail and to keep from post-holing up to my waist. It could be done without poles, but I'd definitely recommend having them.

At treeline, things open up to blue skies and high-country tundra brightened by the many colors of summer wildflowers. In early-May, these were just beginning to bloom. However, come mid-June, the creek alongside the trail and these upper reaches of high-country should be replete with wildflowers.

Once you crest the saddle, the views are outstanding. To the Northwest, the entire Wild Basin of Rocky Mountain National Park opens up before you. To the North, you'll find Meadow Mountain, elevation 11,632'. I met a local from Allenspark along the trail and he said the views from the summit of Meadow Mountain rival those of St. Vrain because of the perspective looking down into the Wild Basin area.

At mile 3, the trail enters Rocky Mountain National Park. From this point, I could see a faint trail in the snow leading up the rounded ridgeline of St. Vrain Mountain. It's about a 1/2 mile hike from the main trail to the summit with about 700 feet of elevation gain.

The lighter-grey dashed line indicates the path hikers were taking across the snow to the slopes of St. Vrain Mountain. Be sure to hike on durable surfaces (snow, rock, trails) on the summit approach to protect the fragile tundra environment.

The Bear Canyon Loop is a relatively easy 3.3-mile loop that features some of the best views of the Flatirons in Boulder. Explore the full NCAR Bear Canyon Loop hike profile below for trail map, driving directions, and more tips and details to help you enjoy this adventure near Boulder.

Trail Snapshot: Bear Canyon Loop Trail in Boulder

Parking & Trailhead: Bear Canyon Loop Trail

The National Center for Atmospheric Research (NCAR) Trailhead is located about 40 minutes North of Denver. From Denver, follow U.S. Route 36 to Boulder. Take the exit for Table Mesa Drive and follow it West. It will wind through a neighborhood to the end as it winds through the neighborhood and past Bear Creek Elementary School. The road will turn into the Drive for NCAR which winds up and around to a large parking area at the lab.

The Hike: NCAR Bear Canyon Loop Trail

From the NCAR Parking area, hikers can pick up the NCAR trail just West of the main entrance to the building. The trail heads West, over a small ridge, past a water tank, then to a fork in the trail. Both the left and the right fork are considered the NCAR trail and both will lead to the Table Mesa Trail--but the left fork is shorter. At approximately 0.7-mile into the hike, the NCAR Trail will intersect with the Table Mesa Trail. Straight through takes hikers up on a 0.8-mile hike up to Mallory Cave, but for this loop hike, the correct way is to go left/South onto the Table Mesa trail. This first stretch provides some incredible views of the magnificent Flatirons Formations of Boulder. This trail segment heading south goes in and out of a forest grove, then the trail comes to its second important intersection.

At the Bear Canyon Trail intersection, take a left onto the Bear Canyon Trail which follows Bear Creek as it descends East. At about 1.5 miles into the hike, you'll encounter another fork. You can cut off about 1/4 of a mile of the trail by taking the left-hand segment. But the right-hand trail provides more pleasant scenery along the creek. The trail will near a neighborhood then bend to the North. This straight 0.7-mile stretch follows along the Eastern boundary of NCAR. Eventually, it meets up with the NCAR trail, which will lead back on a 1/2 mile stretch to the parking area.

This trail is found just to the left/west of the Lichen Loop trail. These should be well-marked by signs and the Lichen loop trail will immediately cross a footbridge. The Lichen loop is a great option for families with small children being just 1.3-mile loop with about 230' of elevation gain over the course of the hike.

Trees on Heil Valley Ranch Hike near Boulder, CO

Taking the Wapiti trail, hikers will head North through a broad valley punctuated with Ponderosa Pine. After passing an intersection with the Lichen Loop, the Wapiti will soon enter the shade of more ponderosa pines as it makes its way through more rocky and steep terrain. At 2.5 miles in, the Wapiti will meet up with the Ponderosa Loop Trail.

The Ponderosa loop segment offers a great set of views, beginning with views of snowcapped peaks in the west. We recommend taking the Ponderosa loop counter-clockwise, which will take you up to a high point then back down into a beautiful meadow with views all the way out to Left-Hand Reservoir. A second overlook is gained after this section, providing great views out to Indian Peaks Wilderness and Longs Peak in the North. The trail will meet back up with the Wapiti trail for a descent back to the trailhead.

Gregory Canyon Hike to Realization Point

The trail up Gregory Canyon is a moderately challenging hike to Realization Point Trailhead where hikers can pick up two different loop trails. Both loops offer expansive views of the Rocky Mountains in the West and wildflowers along the trail. Explore the full Gregory Canyon-Realization Point hike profile below for trail map, driving directions, and more tips and details to help you enjoy this adventure in Boulder, Colorado.

Trail Snapshot: Gregory Canyon to Realization Point

Parking & Trailhead Information for Gregory Canyon

Hikers have several parking options for the Gregory Canyon Trail: 1) the Gregory Canyon Trailhead, 2) Parking at Chautauqua Park, or 3) along permitted stretches of Baseline Road. The Gregory Canyon Trailhead can be reached by following Baseline Road in Boulder west past Chautauqua park. Gregory Canyon Road is located on the left/South about 1/2 mile West of the park. Parking is allowed along most of the south side of Gregory Canyon Road and there is room for 7-8 vehicles at the trailhead. Both the roadside parking and the small parking area at the Gregory Canyon Trailhead require an access fee. Because of the fee and because this parking area fills quickly most mornings, many hikers opt to park along Baseline or at Chautauqua Park. Another option is to park at the Realization Point Trailhead (another fee parking area) and to hike down through the Canyon.

The Hike: Gregory Canyon Trail to Realization Point

In addition to its proximity to Boulder, this hike sports a number of options and a variety of landscapes. The stretch between Gregory Canyon Trailhead and Realization Point Trailhead is the main artery of all the options in this profile. Because most hikers will begin their adventure at Chautauqua Park, there are a couple 1/2 mile (one-way) approaches: the Baseline Trail or the Meadow Trail. On the upper end of the hike, at Realization Point Trailhead, there are two different loop options that offer beautiful views to the West of seasonal snowcapped peaks. These are the Rangeview/Ute Loop and the Tenderfoot Loop. You can review each of the hike options below to decide which trail combination is best for you.

Gregory Canyon Trailhead to Realization Point Trailhead - 2.4 Miles Round Trip

This segment constitutes the main artery for all the hike options below. The Gregory Canyon Trail begins in the shade along Gregory Canyon Creek and climbs gradually to 0.5 mile where it crosses another small creek. Here the trail becomes more steep, making its way up a ridge via a set of switchbacks. Then the trail descends to a junction. At the junction, the Northern (right) segment leads a short distance up to Flagstaff Road and the Realization Point Trailhead (the destination for this hike as described here), or South (left) to the Long Canyon and Ranger Trails. After hiking the short segment to Flagstaff road, Realization Point Trailhead will be located across the street to the North. Be sure to watch for both cars and cyclists before crossing. If starting at Chautauqua Park and taking the Baseline or Meadow Trails to the Gregory Canyon Trailhead, add approximately 1 mile to this hike, making it 3.4 miles Round Trip.

Gregory Canyon Trailhead to Realization Point Trailhead + Rangeview/Ute Loop - 3.2 Miles Round Trip

After traveling the 1.1 miles up through the canyon to Realization Point, hikers will find two loop options. The first is the shorter Rangeview/Ute Loop. This loop makes a 0.8-mile clockwise circuit around Flagstaff Mountain then joins back up to the trailhead. The loop offers views to the mountains in the West and great viewpoints to take in the changing aspens in the Fall. If starting at Chautauqua Park, add approximately 1 mile to this hike, making it 4.2 miles Round Trip.

Gregory Canyon Trailhead to Realization Point Trailhead + Tenderfoot Loop - 4.7 Miles Round Trip

From Realization Point Trailhead, the Tenderfoot Trail bears to the left (Northwest) and makes for a more demanding loop when compared to the Rangeview/Ute Trail because of both the added distance and the additional elevation loss and gain. At its most northern point, hikers will find a short spur trail leading to a small peak that affords expansive views to the West. If starting at Chautauqua Park, add approximately 1 mile to this hike, making it 5.7 miles Round Trip. By adding the spur trail, it becomes closer to 6 miles total.

Hall Ranch Hike Near Lyons, Colorado

Hall Ranch, just outside of Lyons Colorado, is a hiking, mountain biking, trail running destination that features red sandstone buttes, vast green meadows, and panoramic views of white snowcapped meadows. Tucked into the foothills near the St. Vrain River, the trails at Hall Ranch are a great escape from life in the city. Explore the full Hall Ranch hike profile below for trail map, driving directions, and more tips and details to help you enjoy this adventure in the Boulder County.

Trail Snapshot: Hall Ranch Hike Near Lyons

Directions & Trailhead Information for Hall Ranch Hike

Hall Ranch is situated west of Lyons, Colorado about 16 miles north of Boulder. It's easy to access via the CO 7. There are two trailheads for Hall Ranch. The primary Hall Ranch Trailhead is located off Saint Vrain Drive/CO 7 West, about a mile outside of Lyons. The parking area is located on the North side of the road. This is the best access for most of the hikes and has both restrooms as well as a picnic shelter that can accommodate up to 24 people. The second smaller trailhead is the Antelope Trailhead, located at the end of Antelope Drive just northwest of Lyons. This second trailhead provides access to the Antelope trail, a connector trail described below.

Sandstone Buttes at Hall Ranch

The Hikes: Hall Ranch Hike

There are several options for trails at Hall Ranch:

  • Nighthawk/Bitterbrush Loop - 9.2 Miles RT - +2480' - Moderat

  • Probably the most popular is the Nighthawk Trail/Bitterbrush Loop. The loop starts at the west side of the main trailhead and sports a variety of landscapes: expansive meadows, tall buttes, pinion pines, and 180-degree views at its higher elevations. Starting at the main trail, hikers will soon come to an intersection with the Nighthawk trail and Bitterbrush. For this trail profile, we'll take a clockwise approach, following the Nighthawk trail westward. The Nighthawk trail makes a steady climb to where it tops out at approximately 7700' where it offers great views out to Longs Peak and a panorama of Rocky Mountain National Park. Here, hikers will notice an intersection with the Button Rock trail. This 2-mile out-and-back trail is not part of the loop. Staying on the Nighthawk Trail, it will meet up with the Nelson Loop Trail. Hikers can choose to go right or left, both trail segments will link up with the Bitterbrush after approximately 1 mile. Now about 5.5 miles into the hike, hikers will follow the Bitterbrush Trail as it descends for 3.7 miles back down to the main trailhead.

  • Nelson Loop Trail - 2.2 Mile Loop - +299' - Moderate

  • The Nelson Loop can only be accessed by first hiking either the Nighthawk or the Bitterbrush to where they connect up with the Nelson Loop. If you would like to do a lollipop loop hike, we recommend taking the Bitterbrush up to the Nelson Loop, hiking the loop, then returning via the Bitterbrush. This makes for a 9.6-mile hike. The Nelson Loop features the remnants of the old Nelson Homestead just off of the southern segment of the loop.

  • Nighthawk Trail at Hall Ranch - 9 Miles RT - +1282' - Moderate/h3>

  • The Nighthawk trail can also be hiked as a 9-mile out-and-back trail. However, we recommend the full loop above because it's almost the same total distance and offers a greater variety of landscape. The Nighthawk Trail is hiker-only, so it makes for a great option if you prefer to avoid horse and mountain bike traffic. This trail is our favorite, offering vast meadows of green in the Spring and early Summer with views out to Mt Meeker and other snowcapped peaks.

  • Bitterbrush Trail - 7.4 RT - +898' - Moderate

  • The Bitterbrush Trail is a moderate 3.7 trail that begins at the main trailhead or that can be accessed midway by way of the Antelope Trailhead. Out-and-back, it makes for a 7.4-mile trip.

  • Antelope Trail - 1 Mile Trail Connector +458' - Moderate

  • From the Antelope Trailhead, the 1-mile Antelope Trail takes you west to meet up with the Bitterbrush Trail. Gaining approximately 500' in a mile, it can make for a great 2-mile out-and-back trail run and provides some unique views not available on the longer trails.

  • Button Rock Trail - 2 Mile Trail Connector +220' - Easy

  • The Button Rock Trail leads down to the Sleepy Lion Trail at Button Rock Preserve where hikers can pick up a whole series of trails around Ralph Price Reservoir.

Diamond Lake Hike

The Diamond Lake Trail leads hikers to a high alpine lake nestled in the forest below Jasper Peak in Indian Peaks Wilderness. This 3.5 mile, moderately demanding trail leads to good fishing at Diamond Lake, past a waterfall and multiple cascades, and opens up to the incredible views that make Colorado's high-country famous. Explore the full Diamond Lake hike profile below for trail map, driving directions, and more tips and details to help you enjoy this adventure in the Indian Peaks Wilderness.

Trail Snapshot: Diamond Lake Trail

Directions to Diamond Lake Trail & Trailhead

Drive for approximately for 1hr from Denver to Nederland, Colorado. From Nederland, drive south on CO 119 for about half a mile. Turn right onto CR 130 towards Eldora, then proceed westward through the town of Eldora on Eldorado Avenue which will turn into Hessie Road as it leaves town. At the intersection with CR 111 (4th of July Road) turn right; this will take you to the Fourth of July Trailhead. On the way to the trailhead, you'll pass Buckingham Campground. Though this looks like a trailhead and parking area, drive past it to the actual trailhead. It is important to note that 4th of July Road is a dirt road and only useable by passenger vehicles during the Summer months, and rain and snow can cause the road conditions to be unpredictable. Washouts can make this a 4WD road.

The Hike to Diamond Lake

The hike to Diamond Lake begins at the 4th of July Trailhead by taking the Arapaho Pass Trail #904. The Arapaho Pass trail ascends quickly into Indian Peaks Wilderness area. New views open up about every quarter mile featuring distant waterfalls, trailside cascades, creeks, wildflowers, and expansive mountain views. Hikers will encounter the first trail junction at 1.2 miles in. The correct trail, the Diamond Lake Trail (easy to remember) is to the left/west. The first 1/2 mile on the Diamond Lake Trail heads west along a drainage then descends to Middle Boulder Creek. At approximately 1.7 miles into the hike, the trail follows a bridge over Middle Boulder Creek. This a great place to stop and take in Diamond Lake Falls (pictured below).

After the waterfall, the trail crosses two more creeks then begins a steep ascent through a series of switchbacks. This final trail segment is approximately 1 mile, making the entire one-way hike to Diamond Lake approximately 3.5 miles. This segment from the waterfall to the lake is often covered with snow into early Summer, so orienteering and snow-travel skills are recommended for those who decide to negotiate the snow-covered trail.

Campfires are prohibited at Diamond Lake, but camping is allowed by permit and in the designated sites. For more details on backcountry travel and permits in the Indian Peaks Wilderness area, see the Indian Peaks Wilderness Alliance. The Diamond Lake Trail continues past Diamond Lake into the high country where it meets up with the Devils Thumb trail. Hikers in Indian Peaks should always prepare by packing the 10 Essentials, and have a plan in case they encounter rapidly changing weather conditions. In the summer, this means thunderstorms and lightning that rapidly form, and un-forecasted snowstorms from Fall to early Summer.

At 1.2 miles, the trail will come to a junction. The way up to Diamond Lake Falls and Diamond Lake will follow the left-hand trail. The Diamond Lake Trail first heads west along a drainage then descends to Middle Boulder Creek. This segment from the trail junction to the bridge and waterfall is 0.5 mile.

Eldorado Cascades at Walker Ranch

Eldorado Cascades is tucked back in Walker Ranch near Boulder, Colorado. It's an easy to moderate 1.25 mile hike from the Ethel Harrold Trailhead down to where South Boulder Creek winds through the park and crashes over the boulders blocking its path. Explore the full trail profile below for all the details: tips, trail map, and driving directions to the trailhead.

Trail Snapshot: Eldorado Cascades at Walker Ranch

Eldorado Cascades can be reached from several different trailheads that tie into the Walker Ranch Loop system. However, the shortest and probably easiest access is by starting at the Ethel Harrold Trailhead. See the directions driving directions links on this page, and be sure to make note of your last couples turns because cell phone services are spotty.

The drive up to the trailhead on Flagstaff Road is a beautiful one, but do be aware of the many hikers, climbers, and cyclists along the road. After Flagstaff road, the two roads that lead to the trailhead, Pika, then Bison, are improved dirt roads. These were recently graded when we visited (early April) and were fine to drive. However, 4-wheel drive is probably necessary during the winter months or after early Spring rains or snowfall. The trailhead parking area has a pit toilet and information board. If you are interested in birdwatching, you'll find a Birds of Walker Ranch Chechlist at the board.

The Hike to Eldorado Cascades

The hike begins with expansive views of Walker Ranch and out towards Eldorado Canyon State Park (pictured above). The air was full of the scent of juniper trees, and we found abundant Elk sign in the meadows near the trailhead. The trail winds down to a intermittent stream that was gushing with the early Spring snowmelt. A bridge buried in snow leads across the creek, then the trail skirts the hillside for most of the hike, gradually working its way down to a junction with the Walker Ranch Loop Trail. At the junction, the trail to Boulder Creek and Eldorado Cascades is to the right and takes hikers further downhill to a bridge that crosses South Boulder Creek.

The sound of water is almost always within earshot, and the chirps of a variety of birds fill the air. Shortly before the bridge, hikers may notice a "To Eldorado Canyon" sign and trail on the left side of the Walker Ranch Trail. This leads to Eldorado Canyon State Park, about 3.5 miles away, but does not lead to the cascades. The cascades can be found almost immediately after crossing the bridge that spans South Boulder Creek. Here the trail becomes a series of uneven rock stairs that lead to the top of the cascades (pictured above is view from the top).

"Eldorado Falls" seems to be a local and unofficial name given to this set of cascades. The trail map simply marks them as "falls." On the back side of the cascades, South Boulder Creek seems to disappear under massive boulders that block its path. Here the water slips under the rock then shoots out on the other side in a series of small cascades. The water pools, then pours over another lower cascades (pictured above) before returning to calmer waters.

The hike back is mostly uphill, but it's only about a +500' of elevation gain. The park is open in the winter; however, the trail from the Ethel Harrold trailhead down to the Walker Ranch Loop might become difficult to discern after a blanket of snow. So, the ideal times are Spring through Fall.

Tips & Resources for Hiking to Eldorado Cascades

  • Come Prepared in Spring and Winter: Because the trail is mostly in shade of ponderosa pines, the snow and ice can settle in during both winter and spring. Therefore, we recommend Trekking Poles and/or Traction Devices for this trail (I wish I had brought mine).
  • Exercise Caution Around the cascades: The area around Eldorado Cascades is rocky and uneven. The cascades are also difficult to photograph because of how it's tucked back into the canyon. For this reason, exercise caution along the slippery rock and near the waters of South Boulder Creek.
