Yosemite's Royal Arch and Washington Column

This 3d topo shows the north wall of Yosemite Valley from Serenity Crack (5.10b) to North Dome Gully. It includes Washington Column. It is useful for visualizing the standard descent from Washington Column. In 3d the "Death Slabs" section is very easy to see and it is obvious how and why to avoid it.

While this model is no substitute for a map and good beta, it presents the cliffs in a form which is much easier to grasp ;-)

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.
