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.

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.

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.
