For many miles he wound along the Ohio, as far as the Falls.

He also found the Big Bone Lick with its mammoth fossils.
In July, 1770, Daniel returned to the Red River camp and there met Squire Boone with another pack of supplies.

The two brothers continued their hunting and exploration together for some months, chiefly in Jessamine County, where two caves still bear Boone's name.

In that winter they even braved the Green River ground, whence had come the hunting Shawanoes who had taken Daniel's first fruits a year before.
In the same year (1770) there had come into Kentucky from the Yadkin another party of hunters, called, from their lengthy sojourn in the twilight zone, the Long Hunters.

One of these, Gasper Mansker, afterwards related how the Long Hunters were startled one day by hearing sounds such as no buffalo or turkey ever made, and how Mansker himself stole silently under cover of the trees towards the place whence the strange noises came, and descried Daniel Boone prone on his back with a deerskin under him, his famous tall black hat beside him and his mouth opened wide in joyous but apparently none too tuneful song.
