Beginning in the 1670's, Spanish journals record bison in Florida, especially in the panhandle, and in neighboring states. While these bison were commonly hunted by Native Americans and Spaniards, and bison robes were common possessions, fewer than ten bison were recorded as harvested in a day. Bison herds seem to have consisted of dozens, perhaps rarely a few hundred, animals. The Illinois tall-grass prairies supported bison herds of at least hundreds of animals. This habitat extended across Indiana into Ohio and western Kentucky. In 1769, Daniel Boone relates seeing thousands of buffalo on the western Kentucky bluegrass. Such numbers occurred primarily at mineral licks that attracted bison from all directions, as evidenced by numerous radiating traces. Also in 1769, George Washington killed bison in the Kanawha Valley of West Virginia. At this time bison were rather plentiful in the Ohio River Valley. Soon, bison were part of a commercial trade, mostly of hides, along the Ohio River and its major tributaries, including the Wabash, Kentucky, Tennessee and Cumberland Rivers. Downstream, New Orleans became a shipping point for pelts to Europe and for salted meat to the West Indies to feed enslaved workers.
