Comments
DjLv-VP2, Treesbank: The wood-bearing sand dated by Y-415 is tentatively interpreted as part of the Assiniboine delta laid down in glacial Lake Agassiz. The sand overlies 2.4-3.0 m of gravel and sand resting on till. It is overlain by about 7.6 m of sand containing a fossil soil horizon, with aeolian sand at the surface.
