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.
