Two weeks ago Monday I drove up to Mt. Rainier. The mountain was in the clouds.
This past Monday, the 10th, I went up there again. At 1:30 the mountain was visible. By 3:00 when I was up at the same place I'd been the prior week, it was gone. The third picture is at 4:00pm today taken from the webcam.
