Los Angeles Basin region: Verdugo Mountains, north side. Off the 210 freeway east bound La Tuna Canyon Road exit opposite this exit is a road that starts out paved. (Hostetter Mountainway) follow this road that parallels the freeway east till a dirt road forks off on the right (southeast). Don't take the road that forks off to the right, stay parallel with the freeway a short distance.
