Glacial drift, undivided (WAQg;0)

State	Washington
Name	Glacial drift, undivided
Geologic age	Pleistocene
Lithologic constituents	Major Unconsolidated > Coarse-detrital > Gravel (Glacial-till, Glacial-outwash) Unconsolidated > Coarse-detrital > Sand (Glacial) Incidental Unconsolidated (Alluvial)
Comments	Primarily located in northeast Washington with some deposits along the Skagit River and near Eatonville. The Hayden Creek and Wingate Hill Drifts are alpine glacial deposits. The drift in northeast Washington was deposited by the Cordilleran Ice Sheet in Late and pre-Late Wisconsin (Stoffel and others, 1991). Most deposits are gravel to fine-grained sand. Finer-grained material (silt and clay) is incidental.
Stratigraphic units	Nespelem silt (in part); Salmon Springs Stade: Wingate Hills Drift, Hayden Creek Drift; Vashon Drift (in part); Sumas Drift
