Lick and Run in Place Names

Orion in Pittsburgh, Pennsylvania, grew up in rural West Virginia on something called Lick Run Road, not far from Mud Lick Road, Turkey Lick Road, and Sanders Run Road. Why do the words lick and run appear in these types of place names? James Hall wrote about animals visiting salt licks in his book Letters from the West. In Kentucky, Big Bone Lick is now a tourist attraction; thousands of years ago, large animals were attracted by its salt deposits. This is part of a complete episode.
