The Tenino Quarry Pool: A priceless gem of Thurston County. The Quarry Pool was originally a working Sandstone Quarry in the late 1800s. It was run by The Hercules Sandstone Company. Its products were used to construct many of Tenino’s buildings after a substantial fire in the early 20th century as well as notable buildings along the West Coast.
July-Aug open Thurs-Sun from noon-5 p.m. Pool may be closed on days with inclement weather
