I'm seldom at a loss for ways to waste an afternoon. If you've ever hiked, climbed or rafted in the West, you'll find plenty of large-scale geomorphological fascination in these panoramas. For instance, this view of the Tavaputs Plateau (the big one in the middle bisected by the deep canyon) nicely complements the image of it which I posted a while ago.

And if you still have some afternoon to kill, browse through this site's photos of hundreds of mountain peaks around the world. Or you can create custom topo maps and satellite photos: cool!
