There were 5 of us. Our route was Crabtree Trailhead --> Bear Lake (Night #1) --> Cherry Creek (Night #2) --> Lower Buck Lake (Night #3) --> Piute Creek (Night #4) --> Hike out back to Crabtree Trailhead. We encountered some snow, a few river/water crossings, lots of mosquitoes, beautiful lakes and waterfalls, gazillions of wild flowers, one coyote, and three cows. Oh, and lots of horses and horse droppings.
Day 1: We started at Crabtree Trailhead on Thursday afternoon after stopping at Summit Ranger Station for our wilderness permits. There is no quota and you don't need to call ahead unless you want to pick up a permit after hours. The staff at the station told us that they thought Piute Creek was passable, but that people were turning around at Cherry Creek due to high water levels. So we decided to stay one night at Bear Lake (Night 1) even though that wasn't on our itinerary, since we figured we'd be turning around early and we wanted to spend at least a couple of nights in the wilderness.
Day 2: Both Piute and Cherry creeks were completely doable, even for "newbies" like us. Cherry Creek was mid-thigh high, and moving very slowly, so no problem. We stayed at a nice camp on the east side of Cherry Creek (Night 2).
Day 3: It was a bit of a slog (boggy) to get down to Upper Buck Lake due to lots of melting snow, but it wasn't too bad, just a bit messy and slippery. Once we got down to Upper Buck, there was an easy crossing to get to over to the east side of Buck Lakes before heading south to lower Buck Lake. We camped at Lower Buck Lake (Night 3). Very pretty spot, but LOTS of mosquitos.
Day 4: We left Lower Buck Lake and headed for Wood Lake. The trail actually crosses the lake at the east end. In dry years, the trail is probably dry, but on our trip, it was submerged. The deepest point was about 4.25'. We crossed this and continued along the south side of Wood Lake. Parts of the trail and hillsides were covered with ice and snow, so we had to scramble up and over these areas, as we weren't comfortable walking over the ice, since it was at a pretty good slope. We finally made it to the end of Wood Lake (it's long and narrow) and continued west along Buck Meadow. Buck Meadow Creek was flowing big and fast and we started to get concerned, as we knew we had to cross it (twice). When we came to the first official crossing, at about 3:00 in the afternoon, we knew it was above our skill level. It was deep and flowing very fast, with rapids just downstream. One of our party had an old map which showed an old trail on the south side of Buck Meadow Creek (the side we were on). We made our way along that side for an hour or so until we found the trail, and we followed that down to where the trail crossed the river. This crossing was much more doable. Although still flowing fast, it was only about thigh high at the deepest point. We set up a rope, just in case. We all made it fine. Then we hiked down to where Cherry Creek crosses the lower loop of the trail. Crossing there was no problem. We headed to Groundhog Meadow and camped just beyond the meadow, on the west side of Piute Creek (Night 4). There are some nice camp spots there, but they are heavily used and not everyone cleans up after themselves. We picked up an entire bag of garbage

Day 5: We hiked the ~5.4 miles back to the trail head, past Grouse Lake and a burned out section which is actually pretty nice with lots of new growth.
Lessons learned: 1) It's good to take river-crossing shoes. I have a pair of Merrell Vapor Glove 2 which I use as camp shoes. Turns out they are excellent water shoes too. They have grippy soles, are light weight and dry fast. 2) Try to avoid pack trails since they are covered with horse droppings. Lots more, but I have to get back to work, and this is already a too-long Trip Report.
