Grad student Matt Dagon takes in view of Bull Lake and recessional Pinedale moraines from the crest of a prominent Pinedale-age terminal moraine, NE side of the Wind River Range, Wyoming.
Grad student and course TA Mike O'Neal checks out fluvial sediments exposed in an exposure of a Pleistocene (Bull Lake-age?) terrace adjacent to the Wind River, Wyoming.
G535 field trippers doing the tourist thing in front of the Grand Tetons, Wyoming (view to west). Back row (l to r): Dave Grow, Mike O'Neal, Matt Dagon, Dr. Bob Hall, Dr. Doug Clark; Front row (l to r): Peggy McGinnis, Allyson Anderson.

Flat tree-covered area beyond base of the rangefront is the late-Pleistocene moraine from the glacier.
Q535 field trippers investigate up-slope facing scarps related to sakungen (non-tectonic gravity failures formed near the crest of ridges) at Aspen Highlands ski area after joining the 1997 Rocky Mountain Friends of the Pleistocene trip. Trench by of ponded sediments beyond people indicated Holocene activity on the sakung. View to SSW.
