Klutlan Glacier soils
2023.2.2.13 · Subseries · 2007-2010
Part of Dr. Paul Sanborn fonds

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:

Sanborn, P. 2010. Soil formation on supraglacial tephra deposits, Klutlan Glacier, Yukon Territory. Canadian Journal of Soil Science 90: 611-618. https://doi.org/10.4141/cjss10042

Part of Dr. Paul Sanborn fonds

These images were obtained on the helicopter flights to and from the Klutlan Glacier study site. The outbound sequence (#5590-5706) 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). On the return leg at the end of the day, the flight initially went upvalley to pick up another party (#5884-5926), before turning north and returning to base camp (#5929-5993).
