We left Lone Pine on Saturday around 10am and made it to Trail Camp by 6. Temperatures were below zero that night.
Sunday we had a late start, leaving camp somewhere around 7am. We made it to the summit by 2pm and were down the hill and in our cars by 10:45pm. I imagine we would have been better off getting a true alpine start at 4am, but getting the extra sleep probably helped us. The hike back down in the dark wasn't too bad except for the fact we were completely exhausted and the unforgiving ice-crusted snow tracks were a hard on the knees.
Have fun and be safe on your way across Trail Crest, especially coming back when you are tired.
