The Arndt Prune Dryer is a specialized agricultural building in Ridgefield, Washington. Built about 1898, it is one of the last traditional farm-built prune dryer buildings in Washington, using a wood fire and natural draft to dry locally grown fruit. Prunes were a major crop in the Vancouver region, as the dried fruit could be shipped economically to markets without refrigeration or spoilage. Read more on Wikipedia
