Clastic debris; Quaternary colluvium, fanglomerate, talus, and glacial deposits; upland-valley margins (IDQg;0)

State	Idaho
Name	Clastic debris; Quaternary colluvium, fanglomerate, talus, and glacial deposits; upland-valley margins
Geologic age	Quaternary
Original map label	Qg
Comments	Unit includes alluvial, glacial, and colluvial deposits in upland valleys. Alluvial deposits include alluvial fan, terrace, stream, and floodplain deposits. Glacial debris includes till (moraine) and outwash deposits. Colluvium is transitional to alluvium, especially in the upper parts of alluvial fans.
Primary rock type	alluvium
Secondary rock type	glacial drift
Other rock types	colluvium
