Yakima Ridge

Yakima Ridge is a long anticline mountain ridge in Yakima County and Benton County in the U.S. state of Washington. From its western end just north of the city of Yakima, the ridge runs east-southeast through the Yakima Training Center to its eastern end at Hanford Reach National Monument and the Hanford Site. Yakima Ridge is paralled on the north by Umtanum Ridge and on the south by the Rattlesnake Hills. Moxee Valley and Black Rock Valley lie south of Yakima Ridge.
