The average resident may not be aware of Susanville’s unique geographical settings. The Susan River is the natural dividing line of the Sierra Nevada and Cascade. It should be noted, that there is a slop over of Sierra and Cascade. This was confirmed by U.S.G.S. as Gallatin Peak, near the south east shore of Eagle Lake, is of granite composition, a typical Sierra trait.

The same is true of Cascade, the Modoc Plateau. and Great Basin. Secret Valley is a prime example as it is intermingled with characteristics of those three geological regions. Of course, lest we forget the Skedaddle Mountains are located on the western edge of the Great Basin  For those that reside here we are fortunate enough to experience this unique and diverse topography.
