Geography comments: "altitude 350 feet... one-quarter mile east of Emigsville, Manchester Township
there is a "carbon14 date" of "3, 722 +/- 200 years (Before Present)" and the fauna is interpreted as spanning the "Late Glacial", "Hypsithermal", and "Recent" based on faunal interpretations
there are several cold-climate rodent species, but the only substantial evidence of a Pleistocene age is the presence of Rangifer tarandus

Taphonomic context: cave
Habitat comments: "The breccia occurred as a ledge... Varying from 0.13 meter to 1.2 meters thick... composed of a matrix of angular, irregular blocks of unweathered dolomite (80 per cent)... rounded, well-weathered limonitic sandstone pebbles" and "brown, sandy, unconsolidated loam, all bound together with travertine"
Methods
Life forms: bats, carnivores, rodents, ungulates, other small mammals
Sampling methods: quarry, screenwash
Sample size: 159
Years: 1963
