One spring (around 1980) in a snowed-in alpine lake in the Cascades we camped on snow in an REI Crestline (A-frame) tent, which has many tie-out points. I used snow anchors I made out of Al sheet, basically little snow flukes with many holes punched in them to decrease the weight. They are around 7″ tall and 5″ wide.
During the night the wind picked up and the tent was flapping, so I put on warm clothes and went out to see what was the matter (my wife declined). Well, the wind was amazingly warm, a “föhn” wind (aka Chinook wind), and it had melted out at least 6″ of snow in a few hours. Many of my stakes were just laying on top of the snow.
And our tent was sitting on a 6″ snow platform since all the snow around it was gone.
It’s amazing how fast snow can melt out in the Cascades!
