Cracks in tundra and bouldery talus on a relatively flat surface along the Denali fault near the West Fork Glacier. Right lateral slip is up to 0.02 +/- 0.01m and north-side-up displacements across the cracks are up to 0.01m. Cracks are discontinuous for 200m along the base of a 1-2m high north-side-up, east-west trending paleoscarp. Site SGSP08, km -2.36. Photo by S. Personius.
