Meadowcroft rockshelter or sand stone re-entrant

MCRS(or SSRE) could be one of the longest occupational sequences in North America, dating to around 15,000 bc. It is in Washington county, Pennsylviania. It was discovered in 1955 by landman/farmer Albert Miller. He immediately contacted the university (university of Pittsburgh), and in 1970 236 sites were excavated.

It is located “High and Dry,” 15m above stream from Cross Creek, a tributary of the Ohio river. *Geological terms are “Sandstone Re-entrant,” or rock shelter (common English). These are overhangs of erosion resistant rock, with further underlays of less resistant presently eroded rock.

Over 20,000 artifacts were uncovered (predominantly flaked stone). Including 2 million animals or plants from 140 identifiable species.
