Geologic units containing glacial drift

Earth material > Unconsolidated material
Glacial drift
A general term applied to all rock material (clay, silt, sand, gravel, boulders) transported by a glacier and deposited directly by or from the ice, or by running water emanating from a glacier.
This category is also used for Glacial sediment.
Stratified glacial sediment

California - Colorado - Idaho - Kentucky - Missouri - Montana - Nevada - New York - Oregon - Utah - Washington - Wyoming
Quaternary glacial deposits (Pleistocene)
Glacial till and moraines. Found at high elevations mostly in the Sierra Nevada and Klamath Mountains.
Glacial drift (Phanerozoic | Cenozoic | Quaternary)
Includes some unclassified glacial deposits
Older glacial drift (Phanerozoic | Cenozoic | Quaternary)
Clastic debris; Quaternary colluvium, fanglomerate, talus, and glacial deposits; upland-valley margins (Quaternary)
Quaternary colluvium, fanglomerate, and talus plus some glacial debris in upland valleys.
Alluvium (Pleistocene to Holocene)
Alluvium; includes glacial deposits along the Ohio River and its tributaries west of Cannelton locks
Glacial deposits, undifferentiated (Pleistocene to Holocene)
Glacial deposits, undifferentiated; shown locally
PLEISTOCENE SERIES (Phanerozoic | Cenozoic | Quaternary | Pleistocene)
PLEISTOCENE SERIES - Loess, till, drift, clay, silt, sand and gravel (shown on cross section, not on map)
Alluvium (Phanerozoic | Cenozoic | Quaternary)
Alluvium: mainly valley fill consisting of silt, sand, and gravel; includes some terrace deposits and glacial drift of Pleistocene age in some areas; locally includes hot spring tufa. The older part of the alluvium, where present, is probably of Pliocene age.
Glacial drift (Phanerozoic | Cenozoic | Quaternary)
Glacial drift: morainal and outwash plain deposits of mountain glaciers; mainly ill-sorted and poorly rounded boulders, cobbles, pebbles, and sand; may include alluvium in places
Morainal deposits (Quaternary)
New York
Glacial and Alluvial Deposits (Quaternary)
Glacial and Alluvial Deposits - underlying bedrock geology unknown.
Glacial and Alluvial Deposits (Quaternary)
Glacial and Alluvial Deposits - underlying bedrock geology unknown.
Glacial and Alluvial Deposits (Quaternary)
Glacial and Alluvial Deposits - underlying bedrock geology unknown.
Glaciofluvial deposits (Pleistocene)
Poorly sorted
Quaternary glacial deposits (Quaternary)
Alluvium (Holocene)
Mostly unconsolidated silt, sand, and gravel valley fill with some clay; includes low-level terrace, marsh, peat, artificial fill, and glacial deposits locally.
Glacial drift, undivided (Pleistocene)
Glacial and glaciofluvial sand, gravel, and till; includes alpine glacier outwash and till as well as some Recent alluvium.
Terrace deposits (Pleistocene)
Unconsolidated to partly consolidated fluvial and glaciofluvial sand and gravel with minor amounts of silt and clay. Includes marine terrace along west coast of the Olympic Peninsula.
Glacial deposits (Phanerozoic | Cenozoic | Quaternary | Pleistocene Holocene)
GLACIAL DEPOSITS--Till and outwash of sand, gravel, and boulders.
Landslide deposits (Phanerozoic | Cenozoic | Quaternary | Pleistocene Holocene)
LANDSLIDE DEPOSITS--Locally includes intermixed landslide and glacial deposits, talus, and rock-glacier deposits.
Undivided surficial deposits (Phanerozoic | Cenozoic | Quaternary | Pleistocene Holocene)
UNDIVIDED SURFICIAL DEPOSITS--Mostly alluvium, colluvium, and glacial and landslide deposits. Primarily in Yellowstone area and Bighorn Mountains.
