GEOLOGIC MAP OF THE SAN JUAN ISLANDS
The San Juan Islands are composed of many different rocks and minerals, some dating back before the Devonian. Glacial activity shaped our Islands into their present-day form. Washington State’s DNR has a Washington State Geologic Information Portal with maps and more information.
SAN JUAN ISLAND WATERSHEDS
The San Juan Islands are split up into 32 major watersheds. A few of these have been selected for extensive testing based on their ecological sensitivity or potential for contamination by non-point pollutants.
