In north-central Indian Peaks Wilderness, in a high mountain valley bounded by Hiamovi Mountain, Cooper Peak, and the improbably named Ooh La La!, lie two lakes: Stone Lake and Upper Lake. I’m mildly amused by the name of the latter. My brain glitches a bit; it wants to add a word. Upper what lake? I’ve recently been to Upper Storm Lake, and I’ve visited Upper Crater Lake. Upper Storm Lake is above Storm Lake, and Upper Crater Lake is above two other Crater Lakes. Shouldn’t this one follow the pattern and be “Upper Stone Lake”?
I put this hike on my “possibles” list some time ago, but waffled back and forth between thinking it was a day hike and a backpacking trip. It’s only about 6.2 miles to Upper Lake, and I often make longer day hikes. But this one had me doubting myself. Typically, my destination lake is the high point of the hike. For this one, the trail passes over a saddle from one drainage to another. The trail climbs to 11,200′, then descends 700′ before a gentle climb to the lakes. By the time the hiker reaches the high point of the hike on the way back to the trailhead, this works out to nearly 4,000′ of total elevation gain in about 8 miles. So it’s a steep one.
Friday, August 7
The Watanga Lake trailhead (I’ve also seen it listed as the Roaring Fork trailhead) is at Arapaho Bay in Lake Granby. It’s about ten miles from US 34, and nine miles of that is dirt road. But the road is very well maintained, has no ruts, and isn’t a washboard road. I’ve driven the Lotus on it a couple of times before. The parking lot has room for maybe two dozen vehicles. On this August weekday morning, there were only four cars there when I arrived at 7:30 am.
Within a few minutes of hitting the trail, we are on the first steep section of the hike, climbing five hundred feet in a bit more than a third of a mile. In contrast, the next thousand feet of elevation gain takes nearly two miles, to the junction with the Roaring Fork trail. (I may be using the incorrect names; I’m assuming we’re on the Watanga Lake trail until that junction. And note that there seem to be many trails called the “Roaring Fork Trail”.) To this point, the trail was alongside Arapaho Creek.
At the trail junction, we make a right turn. After a few minutes, we reach the second steep lift of the hike, gaining another five hundred feet in four-tenths of a mile. The map shows a stream not far from the trail and crossing it at least once. This summer has been quite dry. From the junction until nearly as far as Stone Lake, there isn’t any water. I had plenty of water to get me to the lakes, but I always like to keep track of my water sources.
At the top of the climb, still more than a mile and a half from Stone Lake, the trail passes through a large meadow with expansive views to the south and east, and the dramatic peaks in the heart of Indian Peaks Wilderness are on glorious display. Well, that was mostly true today. The sky was cloudless, but not the deep blue I’m accustomed to when hiking above 11,000′. Today, everything is hazy due to distant wildfires.
After taking in the views from the meadow, the trail descends into Hell Canyon. Here, we come to the third steep section. On the way to Stone Lake, we’re going down this steep bit. We’ll have to go back up it on the return to the trailhead. The footing here is sometimes less than ideal. Trek poles definitely help. Again, we see a five hundred foot elevation change in about four-tenths of a mile.
From the trailhead to the meadow at the top of the hike, the trail moves through moderately dense forest. In Hell Canyon, the forest thins out considerably. In late morning, the sun felt pretty good, but on the return trip, in the heat of early afternoon, the sun was oppressive. I didn’t see any clouds until nearly 3 pm.
There isn’t much traffic on this trail. I met an older couple at the trail junction, and a group of eight backpackers passed me in the meadow. I met two more backpackers about a mile short of Stone Lake. I didn’t see anybody else until I returned to the trailhead. Because there’s not much traffic, the trail becomes less obvious. It’s never difficult to follow, but in the places where it goes through grassy fields, I imagine it would only take a few weeks without hikers for the trail to disappear.
Both Stone Lake and Upper Lake are gorgeous. They are not situated above treeline in a stark cirque, nor in forest with trees lining the shore. There is forest, but it’s sparse and set back from the grassy shore. Hiamovi Tower stands majestically above Upper Lake. There are many small ponds scattered about.
The trail from Stone Lake to Upper Lake isn’t obvious, but that doesn’t matter. I followed the wrong trail and ended up at a campsite. I just headed cross-country toward Upper Lake and was there in a few minutes. The campsite I stumbled upon was the only one I saw, but no doubt there are a few others that are just as nice.
I’ll come back here for a backpacking trip someday. There are two named lakes a short distance down Stone Lake’s outlet. These shouldn’t be too difficult to reach. I’d also like to head north from Upper Lake (toward the saddle just above the beer can in my “Today’s beer” photo) to visit an unnamed lake in the extreme southern part of Rocky Mountain National Park. I’d guess that lake gets very few visitors.
