This environmental patchwork would have been both challenging and productive for the Clovis people of the region.

Diverse plant communities support diverse animal communities, and the transitional environments of the late Pleistocene in the northern Rockies likely supported a rich mix of both resident and seasonally migrating large animals.

The people at Anzick would have had access to mammoths, mastodons, horses, camels, bison, deer, elk, and other prey species that occupied the different habitat types of the region.

The Shields River Valley, where the Anzick site is located, would have been an attractive location for mobile hunter-gatherers for multiple reasons.
