NOTE: Due to resolution changes, the tour has been slightly changed and several placemarks dropped.

I really like the way that this program can bring geology and topography to life. North of Flagstaff, AZ, there is a great collection of extinct volcanoes. This tour gives an idea of what is there. 3D on at 1x, geographic features on, tour speed about 0.2 suggested. See link for further info. San Francisco Mountains Source
