The Simi Hills and the northern reaches of the Santa Monica Mountains National Recreation Area define this landscape on the boundary of Ventura and Los Angeles counties. Established residential enclaves such as Hidden Hills and Lakeside Park sit adjacent to expansive open spaces crisscrossed by historical routes, including the Juan Bautista de Anza National Historic Trail and the Ahmanson Ranch House Trail. The map documents a complex interface between suburban development in Los Angeles and the protected terrain of Laskey Mesa and Cheseboro Canyon.
