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 eastward along Black Rapids Galcier. 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.

Trace of Denali fault along north margin of Canwell Glacier.
Peter Haeussler (Nov 4, 2002)
View north along Richardson Highway where it was offset by the Denali fault. Trans Alaska Pipeline is in the background.
Peter Haeussler (Nov 5, 2002)
Fault trace in trees west of the Mentasta Road. Tallest trees are perhaps 40 feet tall.
Peter Haeussler (Nov 5, 2002)
View south along Tok Cutoff Highway. Here the fault offset the road almost 7 meters.
Peter Haeussler (Nov 5, 2002)
View southeast along the Totschunda fault.
Peter Haeussler (Nov 5, 2002)
Near the southeast extent of the surface rupture of the Totschunda fault thrust faulting pushed the frozen sand and gravel over the snow surface.

View westward up Black Rapids Glacier at large landslides.

Rod March (Nov 7, 2002)
View west over pass between Canwell and Chistochina Glaciers. Two fault traces here may indicate the glacier ice is influencing the fault trace.
Rod March (Nov 7, 2002)
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.
Rod March (Nov 7, 2002)
View north of Denali fault trace at Gillette Pass. this view shows that the surface rupture reoccupies the previous fault scarp. Also the right-lateral offset of these stream gullies has developed since deglaciation in the last 10,000 years or so.
Rod March (Nov 7, 2002)
View down west fork of Chistochina Glacier. Denali fault can be seen crossing the glacier, Wrangell volcanoes in the distance.

View of Denali fault trace in Chistochina River valley.

View of central Alaska Range from the south.
Tim Dawson (Nov 7, 2002)
Denali fault near headwaters of Chistochina River, view to the south. Dark blur at top of photo is rotor blade.
Tim Dawson (Nov 7, 2002)
Denali fault crossing stream near headwaters of Chistochina River. Stream offset was 4.8m. Perhaps better than the previous photo.
Tim Dawson (Nov 8, 2002)
Bone Creek, 5.5 meter offset measured here. The fault trace runs aong the sharp bank edge at the right of the photo, from the bottom center toward the upper right.
Randy Jibson (Nov 9, 2002)
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.
Peter Haeussler (Nov 9, 2002)
Peter Haeussler examining the Denali fault trace on the Susitna Glacier to find matching ice surfaces to determine amount of fault offset.
Peter Haeussler (Nov 9, 2002)
Right step in Denali fault trace on Black Rapids Glacier caused extension of the glacier. Landslide debris in background.

Peter Haeussler prepares to measure the offset of a crevasse on the Canwell Glacier.
Tim Dawson (Nov 9, 2002)
The fault scarp created a waterfall in the transition region between the Denali fault and the Totschunda fault.

Peter Haeussler (Nov 10, 2002)
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.
Peter Haeussler (Nov 10, 2002)
Patty Craw, DGGS, stands in front of the Susitna Glacier thrust fault. The November 3 earthquake started with an M7.2 earthquake along this fault.

Peter Haeussler measures offset of the Susitna Glacier thrust fault.
Peter Haeussler (Nov 10, 2002)
The Susitna Glacier thrust fault southwest of the toe of the Susitna Glacier. The rolled over tundra reflects the fault trace.
Tim Dawson (Nov 10, 2002)
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. (It was snowing when this photo was taken.)

Surface faulting split this tree near the Trans Alaska Pipeline.

The Denali fault offset crevasses on the Canwell Glacier.
Peter Haeussler (Nov 12, 2002)
Right steps in the Denali fault trace on the Canwell Glacier caused large rhombehedral chasms to form. Patty Craw in background. This photo was on the front page of the Anchorage Daily News.
Peter Haeussler (Nov 12, 2002)
Landslide debris on the west fork of the Gakona Glacier. Note helicopter on right for scale! View to east.
Peter Haeussler (Nov 12, 2002)
Fault trace on Gakona Glacier. Tracks are from where geologists measured the fault offset.
Peter Haeussler (Nov 12, 2002)
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.
