Late autumn moonrise in the Okanogan Highland, a plateau-like mountainous area in the U.S. state of Washington and British Columbia, Canada. This highland plateau lies between the Okanogan Valley on its west and the Kettle River on its east, and geologically is an extension of the Thompson Plateau.
The highest summit of the Highland is Big White Mountain, at its northeastern extremity, which is also the highest summit of the Beaverdell Range. Other notable summits are Okanagan Mountain, Little White Mountain, Mount Baldy, and Mount Bonaparte, which is the highest summit in the American portion of the Highland.
The Okanogan Highland is the source of several rivers in addition to the Kettle and West Kettle, including the Sanpoil River.
