Backpacked June 14-15, 2008. The first 4.5 miles were great, the ATV road was still closed, and we met only 3 other people. About 1/2 mile after the split with the Beaver Creek trail, we hit snow, put on our snowshoes, and lost the trail shortly afterwards. The "remnants of an old logging road" are hard to follow with snow still on the ground, and we never found the location of the log bridge where you "forge over Coney Creek once again." So we ended up staying left (south) of the creek. Do not do this; slopes are steep and covered with large boulders & intermittent snow fields. Putting our snowshoes on/off/on/off was tiresome. Find a place to ford if you can't find the log bridge. On the way down we stayed north of the creek, and although we still never found the trail, it was much easier going. We found a place to ford on the way down and re-joined the trail about where we had lost it the day before. Watch out for thin snow bridges covering the creek.
The lake itself is beautiful; it was windy but not actually cold, we saw snowshoe hare, coyote, marmots, and plenty of trout in the lake. The ground within 300 yards of the lake wasn't snowy, but flat spots are hard to find and were slightly mushy. Beautiful.
NOTE: 2007-2008 was a 150% snowpack winter in this area; snow may not persist this late in future years.
