About this map

The Alberhill and Lake Elsinore interface in Riverside County is defined by the steep transition from the Santa Ana Mountains to the Temescal Valley. Much of the western terrain is protected within the Cleveland National Forest, where high points like Trabuco Peak and Los Pinos Peak dominate the skyline. This 2021 survey illustrates a landscape where modern residential developments, such as those along Horse Thief Canyon Rd, push against the drainage systems of Temescal Wash and Lee Lake.

The map reveals the complex topography of the Elsinore Mountains, carved by numerous canyons including Walker Canyon and Rice Canyon. Traces of local aviation and water resources are preserved through labels like the Mc Conville Airstrip and Chiquito Spring, while the county line between Riverside and Orange counties follows the primary ridgeline. This data provides a clear record of recent suburban expansion near the edges of the national forest and the established mining and industrial history of the settlement at Alberhill.
