Quaternary nonmarine deposits (WAQcl;0)

State	Washington
Name	Quaternary nonmarine deposits
Geologic age	Pleistocene
Original map label	Qcl
Comments	Ringold Formation consists of fluvial and lacustrine fanglomerate, conglomerate, sand, silt, clay with minor tephra. Finer materials make up a larger proportion of the Formation but in relatively unknown abundances (Grolier and Bingham, 1971, Schuster and others, 1987). Located near Potholes Reservoir (Ringold) and near Vancouver.
Primary rock type	lake or marine deposit (non-glacial)
Secondary rock type	conglomerate
Other rock types	volcanic ash
