Elizabeth Crozer Campbell

Elizabeth Warder Campbell (née Crozer; August 11, 1893 – December 21, 1971) was an American archeologist, notable for proposing a much earlier date for the presence of man in the desert Southwest than was generally accepted. She worked with her husband William (Bill) Campbell and first proposed that artifacts found along the shores of Lake Mojave and other Pleistocene lakes and rivers of the desert West were contemporaneous with the presence of water. They showed that there were virtually no sites that were not associated with archaic water sources. They hypothesized that the geologic features associated with the artifacts could be used to date the period of human habitation. This is the first use of what has become known as environmental archaeology.
