The community of Alberhill and the growing residential peripheries of Lake Elsinore anchor this 2015 study of the Santa Ana Mountains' eastern slopes. The landscape is defined by the steep transition from the Elsinore Mountains and the heights of Trabuco Peak down into the Temescal Valley. Within the Cleveland National Forest, the map traces the deep drainage networks of Trabuco Canyon and Hot Spring Canyon, illustrating the topographical complexity of the Orange and Riverside County line. Along the canyon floors and valley flats, human imprints range from the Mc Conville Airstrip to a dense network of suburban streets like McVicker Canyon Park Rd and Cherry Blossom Ln. This documentation shows the intersection of protected wilderness areas with the modern expansion of Inland Empire communities, capturing the precise footprint of development near Temescal Wash and Lee Lake.
