Room 10W is a round, partially exposed structure located in the west sector of Salmon Pueblo. It was built during the San Juan period at Salmon and has an estimated diameter of 5m. Room 10W was probably a kiva. No strata or features were identified. The structure underlies Rooms 8, 9, and 11. Based on the position of the room, it probably dates to the early San Juan period of occupation, between 1120 and 1200.
