Three Dike Hill
Three Dike Hill is a 3,430-foot-tall butte in Presidio County, Texas, within Big Bend Ranch State Park in the Chihuahuan Desert. It features a basalt caprock with three dark basalt dikes pushing up through softer tuff and sedimentary rocks. The formation was sketched by Charles Christopher Parry in 1852 during the U.S.–Mexico Boundary Survey. The area has a hot, dry climate, and runoff from the hill drains to the Rio Grande about a mile to the south. The summit rises over 1,000 feet above the Rio Grande in roughly three-quarters of a mile, and about 800 feet above Tapado Canyon in half a mile. The name has not been officially adopted by the U.S. Board on Geographic Names.
