It's 80 miles long and up to 4,000 feet deep with the north canyon walls in Washington State and the south canyon walls in Oregon State. Through millenniums of geologic events, waterfalls have found their home in the Columbia River Gorge. A visit to the area is not complete without a visit to its breathtaking waterfalls.
