Many pioneers settled in Salt Lick from eastern Pennsylvania (Somerset County and other counties) and from Maryland. They came as early as the Revolutionary war - some earlier.

Salt Lick is the northeastern township of Fayette county, and it's inhabitants are principally engaged in the pursuit of agriculture, although there are areas of valuable mineral wealth embraced within it's boundaries. Westmoreland bounds it on the north, Somerset on the east, Chestnut Ridge is on the west, and on the south lies the township of Springfield. The political existences of the township dates from December, 1797, at which time, in accordance with the petition "of sundry inhabitants of the Salt Lick Settlement in the township of Bullskin, praying for a division of said township and that the top of Chestnut Ridge may be the line of separation," the prayer of the petitioners was granted by the court, and the new township became a distinct political unit. Though now officially designated as Salt Lick it retained for years it's popular title "Yough", a name unauthorized but illustrating the tenacity of familiar usage. The name "Salt Lick" was suggested by the licks of salt that mark the principal water course in the township--that is, Indian Creek.
The surface is mountainous, high hills attaining an altitude above the ordinary level, and in the west forming a plateau. Limestone exists in large quantities and coal appears along the line of the water courses. The projected railroad up Indian Creek would develop the coal and other mineral resources of the township by rendering it accessible to market. The township consists of three small villages and one hamlet.
