Looking at Stearns Lake in the Carolyn Holmberg Open Space

The Carolyn Holmburg Perserve at Rock Creek Farm is a small Boulder County Open Space located north of Broomfield on Highway 287.  It is popular with fishermen and locals taking strolls with their kids and dogs.  Located in the middle farm land, it is very pleasant in the spring and fall and is usually snow free in the winter.

Starting out on the Mary Miller Trail

I chose a steamy day in July 2012 (can you say record heat anyone?) to try running the trails in the park so I grabbed my cell phone to track my pace and distance as well to take pictures on the fly. If the pictures in the post don't seem up to snuff, that is why.  In the humid air, my phone was like a wet bar of soap

Farmland stretches off to the right.  The lake is on the left behind the berm.

The route leaves the lake (out of frame to the left) and heads off to the east.

There are several named trails in the area, but the logical route is to leave the parking lot and head due west along the shore of Stearns Lake.  Technially, this is the Mary Miller Trail, but that name is not evident as you leave the parking area. As you head east, you may see Canada Goose, which frequent the Cottonwood-lined shoreline.

The road leading due east that intersects the trail.  The directional sign is on the post to the right.

Close up of the directional sign.  The arrows point down the road.  I am not sure this is how they want people to go.  If you avoid this turn you come to another trail sign further up the road.

On the far eastern side of the lake there is a large gate and dirt road that continues directly eastward.  Attached to the right-hand post of the gate is a trail sign with two arrows.  This sign was just loosely attached with some wire and was twisted in such a way that the arrows were pointing down the road.  This is NOT correct.  While you can take this road, it may be private so when you come to this junction, continue northward until you see a large trail sign pointing to the right.

If you keep going this is the sign that point to to the trail as it forks eastward.

Looking back towards the lake near several interpretive signs.  Farmland is on either side.

From this point of the route, the trail heads eastward along a slight ridge looking down on a working farm.  I chose to turn around when the dirt trail turned to pavement as it connected to a bike path heading under Highway 287.

My turn around point.  This is where the gravel path becomes paved and travels under Highway 287.  Note the farm buildings in the distance.

Back near the trailhead, this is the sign pointing to the Cradleboard Trail, which from this angle heads off to the right.

After running back around the lake, I took a left on the Cradleboard Trail, which heads due south before more curving westward.  The Cradleboard trail comes to a junction at a dirt road.  To return to the parking lot, turn right.

A typical segment of the Cradleboard Trail.  The Flatirons can be seen in the far distance.

The junction where the Cradleboard Trail continues southwest and a dirt road wraps around to the north to return to the parking lot.

One of things I love about Colorado is that "parks" are more often open space rather than green grass and manicured deciduous trees.  The Carolyn Holmberb Preserve is a perfect example.  While not large, it is perfect for a short run, afternoon stroll, or picnic at the shelter in the parking area.

The parking is ahead in the distance

Mountain Views on the Butler Gulch Trail

Butler Gulch,  near the large switchback on the way to Berthoud Pass, is a close-to-Denver alpine journey filled with wildflowers, waterfalls, historic mining ruins, and make-me-move-here scenic views. This trail is fantastic!

The parking area is just the road by a gate

While most of the route follows an old road, it  occasionally gets soggy

Columbine near the trail

Another stream crossing

You get to Butler Gulch by first turning off of Highway 40 at County Road 202 and then heading due west towards the Henderson Mine. Just before the mine, a dirt frontage road splits off and parallels the paved road.  Continue on this dirt road until the parking area right at the junction with the Jones Pass Road.  Park along the side of the road by a large gate.

Monkshead along the trail

The waterfall at 1.5 miles

Indian Paintbrush along the trail

Mosses extend like beach sand from the "forest" of this riparian ecosystem

The lower sections of Butler Gulch are soggy and tree shrouded with several stream crossings and numerous stands of wildflowers. As the trail rises, it comes to a long cascading waterfall at 1.5 miles and finally breaks out of treeline at 1.8 miles. From this point on, the trail travels westward across a wide alpine shelf and finally reaches the remains of the Jean Mine at 2.7 miles.

Heading across the shelf to the mine

The Continental Divide to the north

More flowers because I could not resist

Wildflowers dot as well as carpet this high altitude play land and I found myself irresistibly drawn to them as our group continued on their way. I would scurry to catch up only to be distracted by the latest colorful bauble.

Getting closer to the mine

The mine tailing come into view

The ruins of the Jean Mine are interesting as well.  Purists may be offended by the piles of metal, old cars, and defunct machinery that covers the area, but this is our Colorado history and it has been part of the landscape for good or evil for the last 100 years.

More ruins

Behind the mine and wrapping around the entire area is the Continental Divide.  There is also a small spur trail leading to a shelf that formally contained a small glacial tarn.

Near the mining ruins was a whole field of Indian Paintbrush

When you see clouds like this above treeline, you should run away!  

If you are from the Denver area and are trying to decide whether to petal peep at Diamond Lake in the Indian Peaks Wilderness or on Butler Gulch, choose the latter.  It will be significantly less crowed and may actually have more wildflowers.

Ptarmigan

A White-tailed Ptarmigan (Lagopus leucura) munches on Bistwort in the meadows below Handies Peak in the San Juan Mountains

Numerous lakes, trails, coffee shops, and ski runs have been named for this elusive member of the Grouse family that lives exclusively in the alpine zone.  I have only seen it twice in Colorado. Once was on Mt. Sniktau and the other was on the way to Handies Peak. Their elusiveness may have nothing to do with scarcity but more to do with their superb camouflage.

Compare the rock with the plumage of the Ptarmigan.  At a distance, would you be  able to see them?

In winter they are totally white, while in summer they are a specked brown. Once I realized I was in a flock of them,  I started looking around and they were everywhere but I had to squint and stare to see them against the talus. They eat everything from alpine wildflowers to the twigs of willows. The young start out eating insects and then move on to more tastier fare.

This Ptarmigan still has a little be of white on its underbelly.  These birds are supposed to keep their white tails.  Perhaps this is a juvenile. 

Superbly adapted to the cold, this bird had feathers on its feet and around its nostrils to keep both regions warm. Just thinking about it makes me want to get a pair of down booties!
