View westward up Black Rapids Glacier at large landslides.

Denali fault crossing stream near headwaters of Chistochina River. Stream offset was 4.8m. Perhaps better than the previous photo.

View westward up Black Rapids Glacier at large landslides.

West fork of Chistochina Glacier. Denali fault trace here is parallel to the moraine, indicating that the structure of the glacier ice is influencing the surface trace of the fault.

View down west fork of Chistochina Glacier. Denali fault can be seen crossing the glacier, Wrangell volcanoes in the distance.

Near the southeast extent of the surface rupture of the Totschunda fault thrust faulting pushed the frozen sand and gravel over the snow surface.

Fault trace in trees west of the Mentasta Road. Tallest trees are perhaps 40 feet tall.

View south along Tok Cutoff Highway. Here the fault offset the road almost 7 meters.

View southeast along the Totschunda fault.

At pass west of Delta River. Here there was roughly 5 m of offset. Note the push up in the background. There is permafrost at the bottom of the cracks.

View north along Richardson Highway where it was offset by the Denali fault. Trans Alaska Pipeline is in the background.

View eastward along Black Rapids Glacier. The Denali fault follows the trace of the glacier. These very large rockslides went a mile across the glacier on the right side. Investigations of the headwall of the middle landslide indicate a volume at least as large as that which fell, has dropped a meter or two and is almost ready to fall.
