Till
Dominantly unsorted and unstratified drift, generally unconsolidated, deposited directly by and underneath a glacier without subsequent reworking by meltwater...
Subtopics:
Moraine
Idaho - Missouri - New Mexico - Washington

Idaho

Glacial debris; Late Pleistocene glacial till, outwash, and alluvium of continental glaciers; northern Idaho (Late Pleistocene )
Pleistocene till, moraines and similar unsorted glacial debris.
 Glacial debris; Late Pleistocene till, outwash, and alluvium of valley glaciers; high mountain valleys (Late Pleistocene )
Pleistocene upland valley deposits; commonly derived from alpine glaciation.

Missouri

PLEISTOCENE SERIES (Phanerozoic | Cenozoic | Quaternary | Pleistocene)
PLEISTOCENE SERIES - Loess, till, drift, clay, silt, sand and gravel (shown on cross section, not on map)

New Mexico

glacial deposits (Phanerozoic | Cenozoic | Quaternary)
Glacial deposits; till and outwash: upper and middle Pleistocene

Washington

Glacial drift, undivided (Pleistocene)
Glacial and glaciofluvial sand, gravel, and till; includes alpine glacier outwash and till as well as some Recent alluvium.
 Older glacial drift (Pleistocene)
Till, outwash, and associated interglacial deposits; sorted and unsorted gravel, sand, silt, and clay. Includes peat beds and non-glacial sediments locally. Mostly pre-Wisconsin in age.
Quaternary nonmarine deposits (Pleistocene)
Predominantly a well-cemented, heterogeneous mixture of volcanic gravel, sand, silt, and clay. Contains some till and in western Washington is commonly deeply weathered.
 Younger glacial drift (Pleistocene)
Younger glacial drift, undivided. Till, outwash, and associated deposits; sorted and unsorted sand, gravel, silt, and clay. Includes some alluvium.
