A Multi-Method Approach to Dating: Persistent Occupation of the Alpine Tundra at Rollins Pass, Colorado.

This paper examines chronological methods for reoccupied archaeological sites with surface arrangements of stone features in the alpine tundra. It is challenging to interpret feature dates in the tundra due to sample scarcity and poor context. I use a case study from a communal hunting site in the Rocky Mountains of North America to argue that archaeologists should use multiple dating methods to disentangle complex site formation histories. The High Grade (5BL148) game drive is located in Colorado's Southern Rocky Mountains and includes 30 stone walls, 52 hunting blind pits, and a short line of cairns. Dating results suggest occupations from 4650 b.c.–a.d. 1850, based on artifact typologies, radiocarbon dates on charcoal and bone collagen, and lichenometric dates on stone walls.
