Bolster is a ghost town in Okanogan County, Washington, USA. In 1899, the town was plotted by J.S. McBride, who named it for the Spokane financier Herman Bolster.[1] He sold lots in the new town and at one time there were several stores, a post office and three saloons. The small town of some thirty families traded with Chesaw, each calling the other a 'suburb'. The town's newspaper, The Bolster Drill, could not make any money, and eventually went out of business. In 1909, the post office closed.[2] There was a school in Bolster in 1910, but it was open for only that year.[3]
