Looking east along the Denali rupture near Slate Creek. D. Schwartz (left) and T. Dawson (right) look across a graben that has formed. About 0.1km from this location the fault produced 5-5.5m of right-lateral slip. Near site DS-22, km 143. Photo by P. Montone.
Looking northwest along the Denali rupture near Slate Creek. At this location a graben has formed, P. Montone is standing in the center of the graben. About 0.1km from this location the fault produced 5-5.5m of right-lateral slip. Near site DS-22, km 143. Photo by P. Montone.

Narrow moletrack along the Denali fault rupture near Slate Creek. View is looking west. For scale, note the orange measuring-tape reel in the middle of the photo and the figures of people along the rupture near the horizon. Near site DS-22, km 143. Photo by P. Montone.
Aerial view northeast near Slate Creek at the Denali fault trace where it faulted a terrace riser (right edge of photo). The main fault zone width here is 5.2m across two main strands and right-lateral offset during 2002 measures 5.32 +/- 0.2m. A paleo offset measured at the site shows a combined right-lateral offset of 8.8 +/- 0.2m, the result of 2002 and a previous event. Site DS-22, km 143.17. Photo by T. Dawson.
View south along a terrace riser offset by the Denali fault trace. The main fault zone width here is 5.2m, across two main strands, and the right-lateral offset during 2002 measures 5.32 +/- 0.2m. A paleo offset measured in the same area shows a combined right-lateral offset of 8.8 +/- 0.2m, the result of 2002 and a previous event. P. Montone is visible on the far side of the fault trace.

View south across the Denali fault at an offset terrace riser in a debris-flow gully. The riser is right-laterally offset 4.9 +0.45 -0.7m across a 2-m-wide zone of rupture. The scarp from the penultimate event rupture is located 13m to the south (arrows). It offsets the riser and an inset channel and debris flow 3.4 ± 0.1m. It is possible that some penultimate event slip occurred along the trace of, and was overprinted by, the 2002 rupture as well. Site DS-22, km 143.17. Photo by D. Schwartz.
