The air museum and the bay in Tillamook
The air museum
The Tillamook Air Museum says on its own site that its mission is to interpret, preserve and honor the World War II history of Naval Air Station Tillamook and Hangar B, along with the history of civil and military aviation. Hangar B was completed in August 1943. The Navy commissioned the station in December 1942, and a squadron of eight K-class airships flew anti-submarine patrols and convoy escorts from it. The station was decommissioned for good in 1948. The museum's site describes Hangar B as 1,072 feet long and 192 feet high, covering over seven acres. The other hangar was destroyed by fire in 1992.
The museum's site was listing it as closed every day when we looked, so check with the museum before you visit. See its official site.
Tillamook Bay
Wikipedia describes Tillamook Bay as about six miles long and two miles wide, on the northwest Oregon coast. The Kilchis, Wilson, Trask and Tillamook rivers flow into the bay, and the short Miami River enters its north end. The Bayocean Peninsula, a sandbar about three miles long, helps shelter the bay from the ocean, and Garibaldi is a small fishing village near the bay's opening.
The Tillamook Estuaries Partnership is a nonprofit based in Garibaldi that works to restore the county's rivers and bays. Its site lists habitat restoration, water quality monitoring and community education, and says its water trail guides cover about 200 miles of waterways.
