The Sheratt Library at Southern Utah University has a few interesting items related to Fort Cameron in their digital collection. See them here, here, here, and here. The first is a sketch of the fort in its heyday. The other three are prose descriptions of the fort’s founding, its physical plant, its garrison, and its abandonment.
All the items are from Monuments to Courage: A History of Beaver County, published by the Daughters of Utah Pioneers and Beaver County.
