About this map

Riverside and the agricultural valleys of inland Southern California are captured here at the turn of the century, showing a landscape defined by early irrigation and mining. The Gage Canal and Riverside Canal systems reflect the foundational water infrastructure that supported the region's citrus and farming growth. Significant mineral extraction is evident throughout the hills, including the Alberhill Coal Mine and the notable Cajalco Tin Mine in the El Sobrante de San Jacinto area.

Industrial and social footprints of the era are marked by the Southern California Railway network, connecting settlements like Perris and Elsinore to coastal markets. Landmarks such as the Indian School and various family-named mines like the Gavilan Mine and Goodhope Mine offer specific points of interest for genealogists tracing local history. The map also records the original shoreline of Elsinore Lake and the wetlands of Mystic Lake before modern reclamation significantly altered these water bodies.
