Introduction
The La Sena Mammoth Site is in southwest Nebraska, on the North side of the Medicine Creek Reservoir. Bureau of Reclamation archaeologists Bob Blasing and Brad Coutant discovered the site in 1987 during a routine shoreline survey (Holen 2008, 1). The La Sena site is situated in a high loess-capped terrace (Holen 2008, 1) approximately 200 ft from the former channel of Medicine Creek. The Medicine Creek Reservoir was constructed in the early 1950s and has since caused an estimated 30 m of cut bank to erode since its construction (Holen 2008, 1). Photo 1.1 below shows the La Sena site area post excavation in 2012 when reservoir water levels had dropped below the base of the berm. I carried out field work and collections studies at the La Sena site in 2011 and 2012. Much of the information contained here is based on my experiences at the La Sena site, and my study of the La Sena site publications and artifacts, for my 2015 dissertation (Steeves 2015) (Fig. 1).
