Mount Houston is east of U.S. Highway 59 near the Dyersdale oilfield in north central Harris County. It was founded on the Houston, East and West Texas Railway ten miles from Houston. A post office operated there from 1910 until 1918. In 1914 Mount Houston had two churches, a sawmill, a lumber company, numerous market gardeners, and a population of 100. By the 1980s three churches and three schools were within a mile of the townsite, but the community had not significantly increased in size.
