AI Insight
Indigenous hunters in central Montana used a bison kill site continuously for nearly 700 years before abandoning it despite continued bison abundance in the region. Researchers determined that recurring multi-decade droughts reduced water availability at the site, making it impractical for processing large numbers of animals. The abandonment coincided with a shift toward larger, more coordinated hunting operations that required reliable access to water and other essential resources.
Why it matters
This research demonstrates how climate variability influenced Indigenous hunting practices and settlement patterns in pre-contact North America. Understanding how past societies adapted their resource use strategies in response to environmental changes provides insight into human responses to climate fluctuations and resource management challenges.
For nearly 700 years, Indigenous hunters repeatedly used a bison kill site in central Montana—then suddenly stopped, even though bison were still abundant. Researchers uncovered evidence that recurring, decades-long droughts likely made the site less practical by reducing access to the water needed to process large numbers of animals. At the same time, hunting groups were shifting toward larger, more coordinated operations that required dependable resources and specialized locations.
