Gatecliff was excavated by archaeologist David Hurst Thomas in the 1970s, and the faunal record detailed by Donald Grayson. A total of 16 human occupations were identified at Gatecliffe, spanning between about 5500-5300 BP to 1250 BP; in particular, Gatecliff includes important Archaic period occupations.
Interleaved between these layers are deposits that have no human occupations, but still contain excellent faunal preservation leading to further understanding of the ecology of the Monitor Valley beginning about 6600 years ago.
