Loomis is a census-designated place (CDP) in Okanogan County, Washington, United States. The population was 159 at the 2010 census. Its area is 0.85sqmi, which is all land and no water.
A post office called Loomis has been in operation since 1889.[4] The community was named after J. A. Loomis, a local storekeeper.[5]
On November 3, 1901, J. M. Haggerty was tarred and feathered in Loomis. He made comments to The Spokesman-Review about the lack of success of the Palmer Mountain Tunnel Company. The comments were resented and a mob was waiting for him when he stepped off the stage. During an impromptu mass meeting, "Suddenly a dozen men grabbed Haggerty, and before half the crowd knew what was happening a bucket of tar and pillows were produced." After half an hour of being paraded through the street covered in tar and feathers, he was released.[6]
