Horse Creek Valley is a geographic area along Horse Creek, a tributary of the Savannah River.
 It lies within present-day Aiken County, South Carolina (prior to 1872, in Edgefield District / Edgefield County).
 The area is alternately referred to as "Midland Valley".
 Rising near Vaucluse, South Carolina, Horse Creek enters the Savannah two miles downstream of downtown Augusta, Georgia.
 Other communities along Horse Creek include Graniteville, Warrenville, Gloverville, Langley, Burnettown, Bath, and Clearwater.
 While Horse Creek itself is rather insignificant, its potential for water power led to early examples of Southern industrialization, including a textile mill at Vaucluse (1830) and William Gregg's Graniteville Mill (1845).
 The textile industry continued to play a primary role until the Graniteville Train Derailment and final closure of the Graniteville Mill in 2006. Wild Horse, Colorado
Wild Horse is an unincorporated village in Cheyenne County, Colorado, United States.
 The community takes its name from Wild Horse Creek, and began in 1869 as a cavalry outpost, which soon became a railway station and had expanded to a town by the mid-1870s.
 After a peak of population and business activities in the early 1900s, the town began dwindling by 1917, when most of it burned down in a great fire.
 The town rebuilt, but never at the population or business-service centralization level of its earlier years, and by the 1930s, had begun to dwindle further. Horse Creek, Wyoming
