The trail is at least 90% snow covered. In the places where there was no snow, there was often water on the trail. Many wildflowers were on the snow free ground. There were a few creek crossings that took some time to find a way across without getting wet. Most of the trail in the flat part of the Box Canyon had about 2-5 feet of snow covering it. Some nice waterfalls could be seen cascading down into the canyon.
You will need some pretty good route-finding skills (at least better than ours) to make it to Rachel Lake. Most of the time you pretty much have to wing it, as there is no real trail to speak of. We managed to get ourselves into a nasty bushwhack at one point. However, the snow level was high enough that brush was usually not a problem. Somehow we followed the wrong stream in our attempt to reach Rachel Lake. Looking over the map later, it seems that we took a stream too far north and ended up following it in the direction of Alta Mountain. We dead-ended at a completely snow covered cirque.
