My nephew Peter (the mid-western mountain goat) and I did a quick 2-day loop to Johnson Mountain and back.
8/11/06 After dropping our packs off at the Bald Eagle Mountain trailhead, we drove back and dropped our car off at the Sloan Creek campground, then walked quickly ~3 miles to the Bald Eagle trailhead. We left Sloan Creek later than we would have liked (around noon).
Knowing that sure water was rare on our route, we made good time to Curry Gap (great wildflowers!). As other folks have noted, the transition from abandoned road to trail is gentle. The trail was in great shape. The uphill from Curry Gap to the ridge was more than noticeable, not not remarkably difficult, and we had a fine ridgewalk to June Mountain.
Having started late, the descent to Little Blue Lake was done at dusk, with visibility starting to worsen. Rather than camp at Little Blue, we decided to press on and go the additional 1/2 mile to Big Blue. But, we missed the turn-off in the dark, and ended up camping up on the ridge below Johnson Mountain. Setting up tents, cooking & hanging bear bags by the light of headlamp... Well, the food tasted great!
8/12/06 We awoke to amazing views. We were probably just below 6,000' and above the clouds, with amazing views of Sloan Peak and the Monte Cristo peaks. The moon was out over the Monte Cristo peaks, with the clouds obscuring the valley below us. We used the last of our water for breakfast and tea, and then descended to Upper Blue Lake (the regular sign was broken, and the kind Forest Service had posted a temporary sign, which we had missed). Upper Blue Lake is beautiful, and the water was warm, which surprised us, as our book suggested that it might be frozen over still.
We climbed back up to our camp, and scrambled up to the top of Johnson Mountain (the trail goes up a long way, but the last 600' is on a boot path/scramble). At the end, the path is not for the faint-hearted in two spots, but it can be done. Once on the peak, we had lunch amid the ruined foundations, rusted nails and melted glass of what we presume was a fire look-out. The views of Rainier, Glacier Peak, and Baker were fantastic!
Descending from Johnson Mountain we walked along Pilot Ridge, enjoying the views (mainly to our left). Our only complaint was that we were getting suntanned only on the port side, as our movement west and then north kept us continuously aligned with the sun's movement.
The descent down to the valley was brutal. It is steep, and if we didn't have trekking poles we would have fallen more than once.
There are some large logs available to cross the Sauk, but be careful, the current was very swift, and we crossed with caution.
The bugs weren't bad, except at Curry Gap. If we were to do this again, we'd want to start earlier, and think even more carefully about where and when to get water.
