Geography

We use geography to locate, organize, and describe places on the earth. This site focuses on the Puget Sound and broader Salish Sea regions of Washington state and British Columbia, which may be spatially mapped and subdivided using a variety of physical, political, or human factors.  The information on this site is generally limited to the Salish Sea waters and the surrounding land basin draining into those waters.

Overview

The boundaries of Puget Sound and the Salish Sea are not always consistently defined by scientists and government agencies. This article clarifies the distinctions between oceanographic and watershed-based definitions of these geographic areas.
