Current sensor data for the Bishop Pass instumentation (11,200 ft at Bishop Lakes):
http://cdec.water.ca.gov/cgi-progs/queryDaily?BSHSnow depth at the top of the pass (@12,000 ft) will be a little more than what the sensor shows.
Skiers and snowshoers have been up and over the pass in the last two weeks. A few days ago, reports were indicating solid, patchy snow early morning, and post-holing after noon. Yes, some boots prints in the snow on the switchbacks below the top, but don't count on it remaining. Try to stay on or near the trail above Bishop Lakes, to avoid the major rock-slide area.
Snow is melting fast and run-off is acclerating.
