Columbia River Gorge Hotel, Hood River Oregon

The Columbia River is the largest river in the Pacific Northwest region of North America. American captain Robert Gray and British captain George Vancouver, who explored the river in 1792, proved that it was possible to cross the Columbia Bar. Many of the challenges associated with that feat remain today; even with modern engineering alterations to the mouth of the river, the strong currents and shifting sandbar make it dangerous to pass between the river and the Pacific Ocean.  Source
