Geography
Country: United States
State: Virginia
County: Augusta
Coordinate: 38° 22' N, 79° 5' W
Coordinate basis: stated in text
Time interval: Late Pleistocene
Geography comments: "one mile north of the town of Mt. Solon... the major portion of the bones was removed from the floor of Brown's Cave, although a few... were found in wall cracks in the Cave of the Wooden Steps"
there is a typo in the published longitude value, which reads 30º 22' N. 70º 5' W.
"not a temporal unit... late Pleistocene and early Recent" but Guilday believes extinct megafauna to have survived into the "early post-Wisconsin" and thinks the fauna is "very close in time" to the late Pleistocene "New Paris #4" fauna, and later authors such as Guilday et al. (1964) and Holman (Fossil Snakes of North America) assign it to the late Pleistocene
