Alien Mothership Sighted in Sierra!
When this strange cloud showed up before sunrise, I knew some weather was on the way. Twelve hours later I was sitting out a wind storm in the Royce Lakes Basin, which had gusts of 60mph, so strong they bent the poles of my REI Chrysalis one man ultra lite tent. It shredded(and I mean shredded)my brother's and nephew's emergency tube tents. Good thing I brought plenty of duct tape. "L" Lake, John Muir Wilderness, Sierra Nevada, California, USA. August 2010.
