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 helpful for visualizing the descent from Washington Column. In 3d that the "Death Slabs" section is quite easy to see and it's obvious how and why to avoid it.
While this version 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 information was collected in Yosemite as part of a study of rockfall. As you climb the cliff, try not to consider that.
