Part of a Republic of Texas land grant formerly occupied by Caddo and Cherokee Indians, this cemetery was established in the mid-1850s by plantation owner Alpha Phillips. The first grave, that of his father, William, is marked with a stone cairn. The family cemetery came to be used by neighbors, West Mountain community residents, and transients. A volunteer association was begun in the 1920s to maintain the grounds, and its members have added acreage to the graveyard over the years. Originally known as Old Phillips Cemetery, it has been called West Mountain Cemetery since 1933.
