Cape Disappointment Lighthouse
Located close to the mouth of the Columbia River, this lighthouse was constructed shortly before the Civil War in 1856. It once had a foghorn but it was moved to Seattle for its ineffectiveness against the crashing decibels of the waves. The lighthouse currently has a fourth-order Fresnel lens - the only one powerful enough to cut through the thick mist. The odd name for the cape apparently comes from the chagrin experienced by the first settlers when they found nary a trading ship carrying goods.
