Note helicopter on right for scale!

The fault trace runs along the sharp bank edge at the right of the photo, from the bottom center toward the upper right.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_1 <![CDATA[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.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_2 <![CDATA[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.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_3 <![CDATA[Trace of Denali fault along north margin of Canwell Glacier.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_4 <![CDATA[View westward up Black Rapids Glacier at large landslides.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_5 <![CDATA[View westward up Black Rapids Glacier at large landslides.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_6 <![CDATA[View westward up Black Rapids Glacier at large landslides.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_7 <![CDATA[View west over pass between Canwell and Chistochina Glaciers. Two fault traces here may indicate the glacier ice is influencing the fault trace.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_8 <![CDATA[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.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_9 <![CDATA[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.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_10 <![CDATA[View down west fork of Chistochina Glacier. Denali fault can be seen crossing the glacier, Wrangell volcanoes in the distance.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_11 <![CDATA[Fault trace in trees west of the Mentasta Road. Tallest trees are perhaps 40 feet tall.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_12 <![CDATA[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.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_13 <![CDATA[Peter Haeussler examining the Denali fault trace on the Susitna Glacier to find matching ice surfaces to determine amount of fault offset.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_14 <![CDATA[Right step in Denali fault trace on Black Rapids Glacier caused extension of the glacier.

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.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_17 <![CDATA[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.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_18 <![CDATA[Peter Haeussler measures offset of the Susitna Glacier thrust fault.]]> http://gallery.usgs.gov/photos/eiy4Cpo00V_19 <![CDATA[The Susitna Glacier thrust fault southwest of the toe of the Susitna Glacier.
