Great trek, though we weren't able to do the entire loop. We set out Friday, April 20th and got in 4 miles up a series of switchbacks before setting up camp (we got a late start, around 6 pm before we got across the dam).
The weather was awesome Friday and Saturday morning. We set off aroung 10 am from our campground through the burned out forest, to Bee Hive, where 3 feet of snow caused us to temporarily lose trail. We also saw some fresh bear tracks near Bee Hive.
We moved on to Lake Vernon and stopped for a quick lunch at 1:30. The next mile was up a steep rock face, with switchbacks. Once we got to the top the trail was once again buried under snow. It took us a good 30 minutes to find the trail again. For the next hour we moved maybe one mile as the snow hid the trail and we were lucky to find small patches of bare ground to get us back on our course. Finally, around 4 pm, with the weather closing in, we chose to turn around. We would have had another 2 or 3 miles at altitude, and none of us wanted to get stuck staying the night, or worse, getting lost (we have jobs and families to get back to after all), so we headed back down. At Lake Vernon, the weather caught up with us. It snowed from then until we got back down to about 6,000 feet, at which point, snow turned into rain. We chose to move on to our original camp, at made it back by 8 pm (we walked 16 miles that day), just in time to start a fire in the rain (amazingly, we were able to). We hit the tents and got dry shortly after. The next morning we woke up with about 5 inches of snow on the ground and made our way down the last 4 miles to the car. Overall and awesome trip, with awesome views. Even with the bad weather and covered trail, it was well worth the weekend trip. We still put in 26 miles total.
By the way, before we headed out, the rangers assured us that the snow was "a couple inches, patchy at best". Apparently they haven't been on the trail lately.
