The Santa Ana River flows through the northern reaches of this territory, anchoring a landscape where emerging citrus agriculture and heavy mining intersected at the turn of the century. Irrigation infrastructure like the Gage Canal and arterial routes such as Magnolia Avenue reflect the planned growth of Riverside, while the southern regions remain dominated by the expansive Elsinore Lake and the San Jacinto Valley.
