From the plaque:
Within this valley was laid
part of the scene, and here resided a number of the characters
portrayed in Helen Hunt Jackson's historical novel, 'Ramona,'
which depicted life and presented the status of the Indians
on many great ranchos in early California beginning around
the 1850s. The story, dramatized by the late Garnet Holme,
was first presented on this site April 13, 1923, becoming
an annual event.
Marker placed by California Centennial Commission in cooperation with Ramona Pageant Association, Inc. Dedicated April 22, 1950.
