As early as 1818, Don Leandro Serrano was in Temescal Valley. Here he had cattle, sheep, cultivated the land, and set out orchards. The boulder placed by residents of Temescal Valley marks the site of the first house in Riverside County which was erected by Leandro Serrano about May 1824.

Many of these plaques have since been recast or their texts revised. The California Historical Landmarks program and its current texts are maintained by the California Office of Historic Preservation. California Office of Historic Preservation ↗
