While I was not at Mt. Whitney this weekend, I was in the Hoover Lakes area, below Bridgeport on Saturday. It snowed on the hike and the winds were so brutal I had to turn around. The gusts were probably 60 MPH and the clouds so dark and forbidding that I bailed on the hike after 3 miles. The weather was incredibly nasty for this time of year. Sunday morning I was planning a hike to Thousand Islands lake out of Mammoth but I awoke with an inch of fresh snow and it was still snowing as I drove home on 395. The snow stopped about 15 miles north of Bishop.
As I was driving by Whitney on 395, I couldn't see any snow on the mountains, but the area was covered by clouds, though not dark or ominous looking clouds. So my weekend was ruined by one aborted hike and one hike not attempted because of very cold, snowy conditions at Mammoth.
For anyone attempting hiking in the Sierras in the coming days, be prepared for unseasonably windy, cold and snowy conditions. I'm assuming this is just a fluke and sunny weather will soon return, but be prepared in any case. Shorts and a T-shirt didn't cut it during this past weekend.
