Mountains as Crossroads: Temporal and Spatial Patterns of High Elevation Activity in the Greater Yellowstone Ecosystem, USA
In the archaeological literature, mountains are often portrayed as the boundaries between inhabited spaces. Yet occupying high elevations may have been an adaptive choice for ancient peoples, as rapidly changing elevations also offer variation in climate and resources over a relatively small area. …
