Great bison belt

Grassland from Alaska to the Gulf of Mexico around 9000 BC

The great bison belt is a tract of rich grassland that ran from Alaska to the Gulf of Mexico from around 9000 BC. The great bison belt was supported by spring and early summer rainfall that allowed short grasses to grow. These grasses retain their moisture at the roots which allowed for grazing ungulates such as bison to find high-quality nutritious food in autumn.
