The eastern flank of the Mackenzie Mountains has a complex history of multiple glaciations by both the Laurentide and Cordilleran ice sheets, recorded in thick sequences of glacial sediments that were documented at 3 locations (Katherine Creek, Little Bear River, Inlin Brook) by:
Duk-Rodkin, A., R.W. Barendregt, C. Tarnocai, and F.M. Phillips. 1996. Late Tertiary to late Quaternary record in the Mackenzie Mountains, Northwest Territories, Canada: stratigraphy, paleosols, paleomagnetism, and chlorine-36. Canadian Journal of Earth Sciences 33 (6): 875-895. https://doi.org/10.1139/e96-066

Of the 3 sites, the exposure on Inlin Brook, a tributary of the Keele River, was the least well-documented, so in summer 2004 Dr. Paul Sanborn joined a field party of the Geological Survey of Canada (GSC) based at Tulita, NWT, and was given helicopter support to visit Inlin Brook (August 5-8). A brief visit was also made to the Little Bear River site.

On August 9-10, Sanborn joined Alejandra Duk-Rodkin (GSC) and Rene Barendregt (U Lethbridge) in helicopter-assisted field work at sites in the Franklin Mountains and elsewhere east of the Mackenzie River.

The BC Ministry of Forest's EP 1148 Long-term Soil Productivity (LTSP) study addresses two key factors— soil porosity and site organic matter—that potentially limit tree growth and site productivity in the timber-harvesting land base and that can be affected by forestry operations.

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).

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).

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:
