HIDALGO BLUFFS. Hidalgo Bluffs (Hidalgo Bluff), an early Brazos River landmark, is off Farm Road 1935 six miles upriver from what was once Washington-on-the-Brazos and three miles from William Penn in northeastern Washington County (at 30°20' N, 96°15' W). The escarpment appears abruptly over the Brazos River and separates the middle Brazos from its less-navigable upper reaches. These steep sandstone cliffs helped boats navigate the Brazos during the era of Antebellum Texas. Hidalgo, the settlement on top of the cliffs, had a river landing below Hidalgo Bluffs during the Republic of Texas era. Sandstone rock from the Hidalgo Bluffs extends across the Brazos River to form Hidalgo Falls, a hazard during the era of steamboat navigation. In the mid-1980s Hidalgo Bluffs was the site of Sommers Gin, the last operating gin in Washington County. Also at the site were three small cemeteries of early settlers.
