Historical Marker · No. 185
Serrano Boulder
Corona, Riverside County · California
Erected by Billy Holcomb Chapter 1069 E Clampus Vitus, 1981
The boulder marks the first house in Riverside County built by somebody who was not from here, Leandro Serrano's, put up about May 1824 and long gone. The valley is named for the houses that came first. Temescal is Spanish carrying a Nahuatl word, temazcalli, meaning a sweathouse — and the Payómkawichum had theirs at the springs along this floor long before Serrano brought cattle up from the Pala asistencia. The landmark counts a first in a valley whose name records what it was second to.
