Stratigraphy
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: date is on "unidentifiable organics" from a mammoth tooth fragment and is a "minimum-limiting date" because of possible contamination fossil is from the "uppermost four meters of sediment" in the pit, but this includes two distinct strata |
Lithology and environment
Primary lithology: | pebbly unlithified calcareous sandstone |
Lithology description: "The lower stratum consists of calcified, gravelly loamy sand; the gravel contains clasts of three to five centimeters in diameter and smaller [and is] two meters or more in thickness. This is overlain by calcareous, fine sandy loam containing considerable fine gravel [that] varies in thickness from less than one meter to more than two meters" | |
Environment: | alluvial fan |
Glacial or sequence phase: | high glacial |
Geology comments: "an old alluvial fan complex" |
