This image is part of the outbound sequence of aerial images obtained on the helicopter flight to the Klutlan Glacier study site. The sequence starts from the base camp at the White River crossing on the Alaska Highway and heads south, to a point just upvalley of the debris-covered terminus (approx. 10-15 km from Alaska border), and turning back north to the landing spot on the Generc River floodplain close to the study site (see Fig. 1 in paper).

With the assistance of the Yukon Geological Survey, Dr. Paul Sanborn was able to visit the terminus of the Klutlan Glacier, a major outlet glacier which originates in the Alaska portion of the St. Elias Mountains. The stagnant terminus has a thick cover of debris, including a large component of White River tephra, providing enough soil material to support a boreal forest. Field work occurred on July 8, 2007, and results were published as:
