About this map

Pebblestone Shut-In serves as the focal point for this section of the Santa Lucia Range, where the Nacimiento River winds through high relief toward Lake Nacimiento. The landscape is defined by its series of distinct peaks and ridges, including Rocky Butte, Black Oak Mtn, and Red Mtn. Historically, the area's resource-driven past is suggested by Keystone Mine Rd and Red Mountain Rd, providing access to these elevated interior lands.

Narrow canyons like McLaughlin Canyon and Carrol Canyon cut through the range, giving way to level clearings such as Almaden Flats and Marmolejo Flats. A complex network of watercourses, including the N Fork Pico Cr and S Fork San Simeon Cr, drains the southern slopes of the range. The map illustrates a contemporary balance between the water management at the reservoir and the preserved ruggedness of the coastal mountains.
