About this map

O'Brien sits along the western finger of the McCloud River Arm, marking a central point of activity within the Shasta National Forest. This landscape is defined by the complex, branching shoreline of Shasta Lake, where the rising waters have created distinct features like O'Brien Creek Inlet and Salt Creek Inlet. The topography is dominated by significant elevations such as O'Brien Mtn and the distinct formation of North Gray Rocks to the east.

Transportation through this difficult terrain is centered on the corridor crossing the Pit River Bridge, connecting the north and south banks. Recreational and local geography is well-documented through named coves and landings, including Bailey Cove, Hirz Bay, and the shoreline at Salt Creek N. Beach. The map also identifies landforms now surrounded by water, such as Beaver Island and Ski Island, providing a clear view of how the reservoir has reshaped the original river valleys of Potter Creek and Marble Creek.
