GLACIOLACUSTRINE DEPOSITS: well-stratified sand, silt and minor clay deposited in lakes impounded by glacial ice; may have a smooth or kettled surface pattern due to melting of buried glacial ice. Sediments form poorly drained areas with peaty blankets.Thermokarsting is common. Glaciolacustrine deposits are found in an unnamed tributary to Anvil Creek, in the northwest corner of the map.


MATERIAL:
GLACIOFLUVIAL DEPOSITS: stratified to massive; poorly to well sorted; gravel and sand with minor silt and cobbles; deposited by meltwater originating from glacial ice. Common in Rose and Anvil Creek valleys


MATERIAL:
BEDROCK: The map area is underlain by rocks of North American affinity and the Anvil plutonic suite. North American rocks underlie the southern half and uppermost northeast part of the map area and consist of the Lower Cambrian Mt. Mye formation, the Cambrian to Lower Ordovician Vangorda formation, and the Lower Ordovician to Silurian Menzie Creek formation. Late- and post-metamorphic Cretaceous intrusions of the Anvil plutonic suite cut the metamorphic stratigraphy and form the core of the Anvil Range (Jennings and Jilson, 1986).

DESCRIPTION:
common on plateau summits and ridges of the Anvil Range.


MATERIAL:
ORGANIC DEPOSITS: peat and woody material; occurring as a flat to gently sloping plain; overlie lacustrine, till, or poorly drained glaciofluvial and alluvial deposits but rarely form a dominant geologic unit.  Permafrost is commonly present within 1m of the surface. Localized palsa development occurs in more poorly drained organic deposits.

DESCRIPTION:
consisting of woody sedge peat, variable thickness.  White River ash accumulations are commonly associated with poorly drained peaty areas.

MATERIAL:
BEDROCK: The map area is underlain by rocks of North American affinity and Yukon-Tanana Terrane. North American rocks underlie the northeast part of the map area and consist of the Lower Cambrian Mt. Mye formation, the Cambrian to Lower Ordovician Vangorda formation, the Lower Ordovician to Silurian Menzie Creek formation, and post-Mississippian Anvil Range Group basalts.  Rocks adjacent to Tintina Fault consist of Permian and older rocks of Yukon-Tanana Terrane (Jennings and Jilson, 1986).
