Foss is an unincorporated community in Tillamook County, Oregon, United States. It is about 4miles east of Mohler and Oregon Route 53, near the Nehalem River.[1] Foss is the site of an important river flood gauge.[2]
Foss was named for Herbert Foss, who owned timber in the area.[3] Foss post office ran from 1928 to 1943, and Foss station on the Southern Pacific Railroad (now the Port of Tillamook Bay Railroad) was established shortly after the post office.[3] Camp Nehalem (also known as Camp Foss), a Civilian Conservation Corps (CCC) camp northeast of Foss, had a Foss mailing address.[4]
Foss is only 474 acres in area. It lies in the Northwestern region of Oregon at a low elevation near the ocean surrounded by the highest mountains of the Oregon Coastal Range.
Foss has a borderline cool-summer Mediterranean and oceanic climate with cool, extremely rainy winters, with only 2 inches of snowfall annually, while the summers are mild with light precipitation. Because it lies at a low elevation surrounded by higher mountains near the ocean, heavy amounts of moisture get trapped in the region resulting in plentiful and heavy rainfall.
