Yosemite's Glacier Point featuring the 4-Mile trail and the Ledge Trail

This is a 3d topo map of Yosemite's Glacier Point showing two of the trails which connect Glacier Point to the valley floor. The 4-mile trail is a steep and strenuous hike. The Ledge trail is an insane scramble over dangerous steep terrain, so dangerous that the trail was officially closed years ago following a number of fatalities. You can still climb it (people climb far sillier rocks in Yosemite) but don't say you weren't warned.

This model may not be used as a navigation aid and the accuracy of the routes shown is not guaranteed. The model was made using Lidar data from http://opentopo.sdsc.edu/ which was collected to study rockfall. Keep that in mind if you are considering the Ledge route.

Here is my video tutorial showing how to make 3d prints from Lidar https://www.youtube.com/watch?v=t4-ICkvyJv0
