Caption on back of photo: "#1. This picture was taken by Dr. Carl Falcon when we were surveying Bennett Creek for the possibilities for hydro exploitation. This picture was taken to show the upper end of a narrow (23') canyon and the drop in water in a certain mileage. Myself in the center of the snap, I label this No. 1 in a series. Bill Clark 1941"

WDA's Comments, 2013 Jul 10: One of the things they did while they were waiting for the permafrost to thaw in the sampling test pits was to survey Bennett Creek and Borden, Mcleod and Grizzly Creeks for water supplies and water heads that could be utilized in hydraulic mining to wash the gravel into sluice boxes using large monitors such as were used and are used at Dawson City, YT, and elsewhere. This photo shows ice forming in the fall and therefore it belongs late in Bill Clark's sequence, not first.
