Black’s Fork

“Emerging from the river plain we entered upon another mauvaise terre, with knobs and elevations of clay and green gault, striped and banded with lines of stone and pebbles: it was a barren, desolate spot, the divide between the Green River and its western influent, the shallow and somewhat sluggish Black’s Fork. The name is derived from an old trader: it is called by the Snakes Ongo Ogwe Pa, or ‘Pine-tree Stream;’ it rises in the Bear-River Mountains, drains the swamps and lakelets on the way, and bifurcates in its upper bed, forming two principal branches, Ham’s Fork and Muddy Fork.”
