This study examines prehistoric use of the Stillwater Marsh in the Carson Desert of western Nevada and the adjacent Stillwater Mountains based on an archaeological survey undertaken in 1980 and 1981, and excavations conducted in 1987. Much of the argument about the use of wetlands revolved around whether they were used be sedentary hunter-gatherers, were just one stop of a family’s seasonal round, or were used only as backup resources. As a result, this report focuses on the issues of hunter-gatherer subsistence and mobility.
