The Salt Fork of the Brazos River is one of three forks that meet to make up the main stem of the Brazos. The main stem begins when the Salt Fork joins the Double Mountain Fork near Aspermont in Stonewall County. The Salt Fork travels about 186 river miles from its beginning in Crosby County in West Texas, passing through Garza and Kent counties, to where it reaches the main stem.

This segment of the Brazos River, which is usually intermittent and shallow, crosses geological formations exceedingly high in salt content contributing to the high levels of dissolved minerals that can be found in the Brazos downstream. Evidence of the salt’s source can be found in the “salt flats” that stretch along the river in Stonewall County. For a full-sized map, click here.
