- Denim is a sturdy cotton warp-faced textile in which the weft passes under two or more warp threads. This twill weave produces a diagonal ribbing that distinguishes it from cotton duck. Denim, as it is recognized today, was first produced in Nîmes, France.
- Deception Pass Bridge (Wikipedia)
Deception Pass Bridge is the common name for two two-lane bridges on Washington State Route 20 connecting Whidbey Island in Island County, to Fidalgo Island in Skagit County, in the U.S. state of Washington. It was a Washington State Highways project, and included project elements built by young workers from the Civilian Conservation Corps. Completion of the bridge was a factor in the decision to build Naval Air Station Whidbey Island and helped Oak Harbor flourish. The bridge is a commonly photographed landmark of the Puget Sound region.
