The Okanagan Highland (in US-American parlance Okanogan Highlands ) is a hilly high plateau in the Canadian province of British Columbia and in the US state of Washington . Rounded mountains of up to 8,000 ft (approx. 2,400 m) in height and deep, narrow valleys are characteristic of the region.
BC Geographical Names , a service of the British Columbia Integrated Land Management Bureau , defines the Okanagan Highland as an area extending south from the Shuswap River and the Coldstream Valley east of Vernon for over 85 mi (137 km) to the 49th parallel (the border between Canada and the United States ) and into Washington State. It lies between the Monashee Mountains to the east and the Thompson Plateau and Okanagan Valley to the west. The eastern boundary of the Okanagan Highland is clearly defined by the valley of the Kettle River . The western border is arbitrary and difficult to determine because there are no geographic features between Penticton in the Okanagan Valley and Lumby in the Coldstream Valley to which it could be attached.
The Washington State Department of Natural Resources describes the "Okanogan Highlands" as a larger area that extends east of the Cascade Range and north of the Columbia Basin to northern Idaho and the Shuswap Highland in British Columbia. This region includes Franklin Delano Roosevelt Lake (the dammed Columbia River above the Grand Coulee Dam ), the Kettle River Range, and the southern portion of the Monashee Mountains .
The highest peak in the highlands is Big White Mountain on its northeastern foothills, which is also the highest peak of the Beaverdell Range , a mountain range that extends south of Big White Mountain between the Kettle and the West Kettle River stretches. Other notable peaks include Okanagan Mountain , Little White Mountain , Mount Baldy, Mount Hull and Mount Bonaparte, the latter being the highest peak in the US highlands.
The Okanagan Highland is the source of several rivers besides the Kettle and West Kettle, including the Sanpoil River .
