Long-tailed Jaeger chick, Alaska. Photo taken at Icy Cape study site. Icy Cape is part of the National Petroleum Reserve-Alaska (NPR-A) on the Arctic Coastal Plain. This was one of many study site locations of waterbird-oriented ecosystem studies in the National Petroleum Reserve-Alaska from 1974-1992.

Collecting habitat information at a Baird's Sandpiper nest study site at Point Storkersen on the Arctic coastal plain of Alaska. This was one of many study site locations of waterbird-oriented ecosystem studies in the National Petroleum Reserve-Alaska from 1974-1992.

Caribou on the tundra at Point Storkersen on the Arctic coastal plain of Alaska. This was one of many study site locations of waterbird-oriented ecosystem studies in the National Petroleum Reserve-Alaska from 1974-1992.

Banded Buff-breasted Sandpiper chick at Point Storkersen on the Arctic coastal plain of Alaska. This was one of many study site locations of waterbird-oriented ecosystem studies in the National Petroleum Reserve-Alaska from 1974-1992.

Photo of moss campion flowering at Point Storkersen on the Arctic coastal plain of Alaska. Moss campion or cushion pink, is a small mountain-dwelling wildflower that is common all over the high arctic and tundra. This was one of many study site locations of waterbird-oriented ecosystem studies in the National Petroleum Reserve-Alaska from 1974-1992.

Shorebird nests and broods were monitored daily as part of a long-term study to determine reproductive success of multiple species. The tundra habitat around Pt. Storkersen supports a diversity of shorebird and waterfowl species.

Northwest Island Lake located in the Teshekpuk Lake Special Management Area of the National Petroleum Reserve-Alaska (NPR-A) on the Arctic Coastal Plain. This area provides important habitat for migratory birds. This was one of many study site locations of waterbird-oriented ecosystem studies in the National Petroleum Reserve-Alaska from 1974-1992.

Two Arctic Foxes at Point Storkersen on the Arctic coastal plain of Alaska. This was one of many study site locations of waterbird-oriented ecosystem studies in the National Petroleum Reserve-Alaska from 1974-1992.

A flock of waterfowl flying over Izembek Lagoon on the outskirts of Izembek National Wildlife Refuge on the Alaska Peninsula. Scientists observed the response of Black Brant and other geese to the disturbance of aircraft overflights during a long-term study in the 1980s.

Aerial oblique of Lemon Creek Glacier taken on August 24, 1969.

Repeat oblique photographs of Gulkana glaciers in Alaska.  1967, Unknown USGS photographer. 2016, L. Sass, USGS.

Gulkana Glacier. Ice flowing from four tributaries unites to form the main glacier. Irregular and folded medial moraines suggest that this glacier surges, but no recent advances have been observed.  In recent decades the glacier has been shrinking rapidly; note the large barren area in front of the terminus recently exposed by the melting ice.

Repeat oblique photographs of Wolverine glacier in Alaska.  1966 image by unknown USGS photographer; 2015 image by L. Sass, USGS.

Wolverine Glacier. The glacier heads in a broad basin but terminates in a narrow gorge. Crevasses indicate this glacier is flowing quite rapidly. Relatively little retreat in recent decades is demonstrated by the narrow areas of recently exposed bedrock along the margins of the ice. Seward district, Alaska Gulf region, Alaska. September 3, 1966.

Uplifted sea floor at Cape Cleare, Montague Island, Prince William Sound, in the area of greatest recorded tectonic uplift on land (33 feet). The very gently sloping flat rocky surface with the white coating which lies between the cliffs and the water is about a quarter of a mile wide. It is a wave-cut surface that was below sea level before the earthquake.

During the earthquake fundamental changes in the level of the earth's crust occurred in south-central Alaska and adjacent off­ shore areas. Uplifted dock on Hinchinbrook Island, Prince William Sound. Land in this area rose about 8 feet during the earthquake, and the dock can now be used only at extremely high tides. 

The modern wave-cut bedrock surface surrounding Middleton Island (the flat surface between the base of the cliffs and the water) was submerged at a comparable stage of tide before the earthquake.

The village of Portage, Alaska at the head of Turnagain Arm of Cook Inlet, is flooded at high tide as a result of 6 feet of tectonic subsidence during the earthquake.
