History and General Information 

Outline of the state of Oregon with "Oregon Heritage Tradition" listed under.
Designation for Pacific Dory Days.
Tillamook County was formed in 1853 from Yamhill and Clatsop counties. The name Tillamook comes from the Tillamook (or Killamook) Tribe.

Dairy farms dominate the county’s fertile valley. It is the home of the world famous Tillamook Cheese Factory. The reforested 355,000-acre “Tillamook Burn” area continues to mature. 

Commercial thinning will become increasingly evident. With 75 miles of scenic coastline, four bays and nine rivers, Tillamook County offers the finest deep-sea and stream fishing, charter and dory boats, clamming, crabbing, beachcombing and hiking. Its forests also furnish excellent hunting.
