The Butterfield Overland Mail Company closed in 1861.The Temescal Butterfield stage station was built five miles (8 km) north of the Temescal Hot Springs, ten miles (16 km) north of Rancho La Laguna station and twenty miles (32 km) south of the Chino Rancho station. The Temescal Butterfield stage station was "at the foot of the Temescal hills, a splendid place to camp, wood and water plenty, and protected from the winds." Temescal had its own post office from February 12, 1861, to November 12, 1861. Around this location, the settlement of Temescal grew over the next few decades. By 1860, Greenwade's Place at Temescal, three miles (4.8 km) north of the stage station, was a polling place for southwestern San Bernardino County.
