Denali Fault: Gakona Glacier
Fault trace on Gakona Glacier. Tracks are from where geologists measured the fault offset.
Denali Fault: Gillette Pass
View northward of mountain near Gillette Pass showing sackung features. Here the mountaintop moved downward like a keystone, producing an uphill-facing scarp. The main Denali fault trace is on the far side of the mountain and a small splay fault is out of view below the photo.

Denali Fault: Alaska Pipeline
View south along the Trans Alaska Pipeline in the zone where it was engineered for the Denali fault. The fault trace passes beneath the pipeline between the 2nd and 3rd slider supports at the far end of the zone. A large arc in the pipe can be seen in the pipe on the right, due to shortening of the zigzag-shaped pipeline trace within the fault zone.

Denali Fault: Susitna Glacier
Helicopters and satellite phones were integral to the geologic field response. Here, Peter Haeussler is calling a seismologist to pass along the discovery of the Susitna Glacier thrust fault. View is to the north up the Susitna Glacier. The Denali fault trace lies in the background where the two landslides can be seen.

Denali Fault: Landslides
View southward toward Mt. McGinnis and two large landslides on the northeastern side. These slides had roughly 40 million cubic meters of material and travelled 10 km down glacier. This is the cover photo of the May 16th, 2003, Science.

View west over pass between Canwell and Chistochina Glaciers. Two fault traces here may indicate the glacier ice is influencing the fault trace.
