From the plaque:
Pochea was one of a cluster
of Indian villages forming the very large settlement of
Pahsitnah, which extended along the ridge east and west
of Ramona Bowl. Pahsitnah was thriving when the Spanish
first passed by in 1774. A tragic story tells of the natives
contracting smallpox from Europeans, a terrible epidemic
spreading, and some survivors fleeing to the area of the
present Soboba Reservation.
Plaque placed by the State Department of Parks of Recreation in cooperation with San Jacinto Valley Museum, Hemet Area Museum Association, Ramona Pageant Association, and Billy Holcomb Chapter of E Clampus Vitus, October 2, 1983.
