Mountain Veil
This view of Desolation Canyon in Utah was taken in January 2005 on a flight from Denver to San Jose. The dry winter air yielded amazing clarity. You can clearly see the rock strata in the stereoview. The entire card is black, with the foreground spilling into your space.

The back of this card has a topo map and a ground-level photo (from a website) of rafters on the river.
