MITCHELL POINT TUNNEL (watch for traffic signals) 130.3 m. [West of Hwy. 730 Junction], was bored through a cliff overhanging the river. In its 385-foot length are hewn five large arched windows overlooking the Columbia. The great projecting rock through which the bore was made was known among the Indians as the Little Storm King, while the sky sweeping mountain above was called the Great Storm King.
While the name Mitchell Point only refers to this geologic formation, the development at Sonny is sometimes referred to as Mitchell Point.

Mitchell Point is about 15 miles east of Cascade Locks and four miles west of Hood River. Little is known about the name, beyond the fact that a trapper named Mitchell lived and died near this location (McArthur 1992).
