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

Life forms: bats, carnivores, rodents, ungulates, other small mammals
Sampling methods: quarry, screenwash
Sample size: 159
