Pioneer Stone Burial Cairns (at Mount Gilead Cemetery). Scattered throughout many of the pioneer cemeteries in Texas are unusual stone structurers, or burial cairns, built by the early settlers to memorialize their dead. Primarily surface structures of native stone, the cairns vary in design and workmanship. Their use, however, is representative of traditional burial customs prevalent in the South during the eighteenth and nineteenth centuries. Although their specific purpose and origin are subject to theory, cairns such as these are outstanding examples of pioneer lore and tradition. #4034
