During August of 1939 an esker-like deposit was observed on the surface of the Middle Teton Glacier in the Grand Teton National Park, Wyoming. The deposit, a slightly sorted gravel and clay ridge, was approximately three feet high, four feet wide, and one hundred yards long. In its north to south course over the glacier, the deposit extended over the top of a boulder that projected approximately eight feet above the ice surface. South of the boulder, the deposit lay in a shallow trough scoured in the glacier. Information received from the mountaineering guide indicates that upon the glacier more than eleven feet of snow was present in the early summer. It appears that under this snow and in contact with the glacial ice the esker-like deposit was formed.
