Leadville Weekend Part 3: Mayflower Gulch to Gold Hill Wildflower Hike

Distance 6 miles round trip
Elevation: 10,996-11,980 ft
Elevation gain: 1,040 ft

Monkshood (Aconitum columbianum), Bistwort (Bistora bistortoides), unknown yellow aster, Aspen Daisy (Erigeron speciosus)

Mayflower Gulch near Copper Mountain is one of my favorite wildflower hikes and we usually go up at least once a year to check it out. It never seems to disappoint. This year was no exception. The fields were filled with many different species, the clouds were building, providing much needed shade to photograph the colorful ones, and the weather was sublime.

The cabins of the Boston Mine seen from the road to Gold Hill

Some of you may have already seen my winter Mayflower Gulch post. Summer or winter, Mayflower Gulch is a destination not to be missed. Don’t stay at the cabins of the Boston Mine however. Instead, be sure to head up the right towards Gold Hill. In the winter this is a bushwhack but in the summer you can follow a dirt road to the top. Most years there will be a slight scramble over the remaining snow cornice. This year was no exception.

The farther up Gold Hill you go, the farther back into the Gulch you can see. Here you can see the trail that heads there.

Many of the most beautiful wildflowers grow along the broad slope that borders this road. I like to shove my telephoto lens into the grasses and play with bringing into focus various layers of the flowers. There are so many, it is hard to choose.

View from Gold Hill looking southwest towards the Climax Mine retaining pond
The views from the ridge of Gold Hill are extraordinary. The green meadows to the south remind me of the Sound of Music. If you listen carefully, you can hear the opening strains of that musical and I swear Julie Andrews is about to come twirling out into the open.

Slightly southwest, you can see the giant retaining pond of the Climax Mine. While not a pretty wilderness sight, its colors do make a nice contrast to all verdant greens.

White Crowned Sparrow (Zontrichia leucohyrus) nests in the central mountains of Colorado. It feeds on the ground scratching backwards with both feet simultaneously.

On this trip we also decided to head up into the Gulch to the farther mine site. Alas, we were almost to the final structure when the storms that had been building decided to start rumbling. Since this area is very exposed, we decided to head out. There were many wildflowers along this route as well, particularly along the stream. If you have time, do both and you won’t be disappointed. Note that the mileage and elevation gain listed in this post does not include the trip to the upper mine.

Diamond Lake

Distance: 5.2 miles RT
Elevation: 10,100-10,940 ft
Elevation Gain: 840 ft


Diamond Lake in July looking south
Diamond Lake is a wildflower Mecca with hordes of shutter bugs circling round and around choice Columbine and Indian paintbrush much like Muslims orbit the Kaaba shrine. Depending upon when you go, you can find flowers lower down near the trailhead or up higher in the large meadow that borders the lake. Go too early e.g. May and June and you will end up trodding through large drifts of snow and soggy expanses of melt water. The lake itself can be shrouded in dark clouds at this time too, which does create its own photo opportunities. I suggest waiting until mid-July, however if you want to wallow in wildflowers.


The Colorado Columbine (Aquilegia ceorulea) grows in meadows, woodlands, rocks, scree from June to August. It is also Colorado's state flower.
Be emotionally prepared to feel the press of humanity if you join the Hajj on weekend. Not only must you get to the parking area very early, but also you will be bumped and prodded by the multitudes trodding by. The Fourth of July trailhead is also the starting point for Dorothy Lake and Arapahoe Glacier so for part of the route you will be joined by more serious hikers. Lake is stocked as well, so anglers join the procession to the lake, some carrying inflatable dinghies to float in.


Chiming Bells (Mertensia ciliata) blooms from June to August along streams and waterfalls.
The trail begins to climb right off the bat and the hiker will traverse small meadows and forested slopes. Flowers exist in both places so keep your eyes open for more rare finds. There are several water crossings that are not arduous and which attract their own flock of water loving flower species like the ubiquitous Chiming Bells, which grow in huge clumps anywhere there is water.


Indian Paintbrush (Castilleja miniata) can be found all over the state in meadows, sagebrush flats, and meadows. It blooms from May to September.
At 1.2 miles the trails splits. Take the left fork and continue until you reach a pleasant waterfall. At this point the trail bends back upon itself and heads back down the valley. I find this feature frustrating and don’t know why the trail does just head straight up to the lake with out looping back. This is a psychological impediment I know. It is hard for us driven Americans to ever think of going backwards. This back tracking is also the steeper portion of the trail. It is in a darker forest with fewer views. Early in the season this is also where the snow can linger.


Diamond Lake
At the top of this steep pitch is a broad meadow with logs strategically placed to protect the sensitive plants. The views return at this point but it is best to sally to the lake where there are plenty of places to sit and snap pictures. I particularly like the stunted conifers here, which are wind blown and artistic. Their flag shapes are testament to the winds that flow down the valley from the north. On more than one trip to the lake, I have been hailed on, so bring rain gear even if the weather is pleasant in the morning.


Diamond Lake in May. A lot colder and more snow
Like the participants in the Hajj, you will be spiritually renewed by your journey to Diamond Lake and if you can go on a weekday, then you will reach this renewal without paying the price without having to follow the butt of the person in front of you.
