Yosemite's Royal Arch Route 3d topo

The Royal Arch Route is the greatest moderate climbing route in Yosemite Valley. This model is so detailed that you can see the very cracks and ledges which climbers ascend.

I made it from a LIDAR dataset available on http://opentopo.sdsc.edu/. The data was collected as part of a study of rockfall in Yosemite. Try not to think about that as you climb the cliff.
