United States Post Office
Backstory and Context
Native Americans had used the site of Okanogan as a hunting and fishing ground long before the arrival of explorers and traders. Okanogan's more modern history dates back to 1886 when a man named Frank J. "Pard" Cummings established a trading post and a ferry service across the Okanogan River, which attracted others to the community. It was named Alma in 1888 and the first post office opened that year as well (Cummings became the first postmaster). The town continued to grow and in 1905 was renamed Pogue after prominent local doctor and orchard grower, Dr. J.I. Pogue. The town's name was changed to Okanogan in 1907.
Presumably, other post offices were built in the coming years but that information is not readily available. In addition to its design and association with an important function of the federal government, the current post office is also notable for the organization that built it: the Works Progress Administration (WPA). The WPA was one of the federal programs that put Americans to work during the Great Depression. Building the post office provided work to local contractors, thereby providng a boost to the local economy (the WPA also funded a number of other building and infrastructure projects in the region). As such, the post office symbolizes the federal government's efforts to help citizens during a difficult period in American history. The building also represents how important the federal government considered Okanogan was at the time.
