Station: CRH94

Station ID: CRH94 [1] [2] [3]
Volcano:
Collector: Westgate, J. A.
Date visited:
NAD83 latitude: 68.25194444
NAD83 longitude: -139.7744444
Default location: No
Location description: Located on the right bank of the Old Crow River, about 65 km by air to the southeast of site CRH47. Twenty-six-m-high exposure comprised predominantly of alluvial silt, clayey silt, and sand that exhibit shallow channel structures, and, in places, contain peat, molluscs, and wood fragments. Near the base of the section, lacustrine or pond deposits of clayey silt to silty clay occur, which enclose pods of tephra up to 25 cm thick. Initially visited by J.V. Matthews Jr., Charles Schweger, and Richard Morlan during the 1980s as part of reconnaissance studies on Quaternary deposits exposed in the bluffs of the Old Crow River. Site designation made by C.R. Harington. Site revisited by John Westgate in 1985 as part of stratigraphic investigations. Coordinates provided as degrees/minutes/seconds in Westgate and others (2013) and converted to decimal degrees; datum not specified, assumed to be NAD83.
