Umtanum Ridge Water Gap

Umtanum Ridge Water Gap is a geologic feature in Washington state in the United States. It includes the Yakima Canyon, and is located between the cities of Ellensburg and Yakima in central Washington. Washington State Route 821 was once the main route between Ellensburg and Yakima. The old highway still runs close to the river through the canyon, with Interstate 82 currently carrying most traffic between Ellensburg and Yakima on large bridges nearby.
