This is Tim's "Wall Tent", with a battery lantern inside. Not sure of the dimensions, but Tim had a queen size air bed in one corner, a folding table in another, I had my full size airbed in another corner, and there was a wood stove in the fourth corner, with all kinds of room in between. Sand Mountain is literally a mountain of sand out in the middle of nowhere. Tim put the tent up by himself, but I helped take it down and it took at least a half hour for the two of us to take it apart and pack up.

In this image, the moon is just starting to light up the mountain.
