San Acacia, NM
“The settlement of San Acacio was named by the Spanish after Saint Acacius, leader of the ten thousand martyrs of Mount Ararat, an early Christian saint who was crowned with thorns from the acacia tree. The hill to the east of the San Acacio cemetery was the location where, in 1855, John W. Garretson fixed the Initial Point for the Principal Meridian and the Base Line. This is the reference point for all topographic maps of the state of New Mexico.
San Acacio became important in 1878 when the Atchison, Topeka and Santa Fe Railway was built through Socorro County on its route along the Rio Grande to El Paso, Texas. It was incorrectly given the official name of San Acacia after the railway came through.”
