From the plaque:
In early descriptions it
was known as Cerrito de las Ranas, meaning the Hill of
the Frogs. In the 1890s this hill became the scene of
mining excitement. Its soil composition, very red in color,
had caused early American settlers to name it Red Hill. This landmark is a physical reminder of our rich State and local history.
