Serrano Tanning Vats

Nearby, two vats were built in 1819 by the Luiseño Indians under the direction of Leandro Serrano, first non-Indian settler in what is now Riverside County. The vats were used in making leather from cow hides. In 1981 the vats were restored and placed here by the Billy Holcomb Chapter of E Clampus Vitus.

Plaque placed by the State Department of Parks of Recreation in cooperation with Temescal Water Company, Hydro Conduit Corporation, Glen Ivy Hot Springs, Phil Porretta family, and Billy Holcomb Chapter of E Clampus Vitus, October 11, 1981.
