2022 Map of Cobblestone Mountain

About this map

Cobblestone Mtn and the surrounding peaks of the Los Padres National Forest anchor this survey of the high backcountry where Ventura and Los Angeles counties meet. The complex hydrology of the region is defined by the Piru Creek Wild and Scenic River, which flows south toward Lake Piru through a landscape of deep cuts like Ruby Canyon and Turtle Canyon. Unique terrain features such as the Big Narrows and Devils Gateway on Agua Blanca Cr illustrate the geological forces at work. Evidence of the area's isolation and rugged character is found in evocative place names like Hole-in-the-Wall, Devils Potrero, and The Pothole, while several remote water sources including Halfway Spring and Pothole Spring indicate essential points for travelers in this arid mountain environment.
