Mt. Hood National Forest is one of the natural treasures of the USA's Pacific Northwest. It covers about 4.4k square km. (around 1.5k square mi.) of territory east of Portland, Oregon. The forest includes Mt. Hood, a potentially active volcano which has a peak elevation of about 2.35k meters or around 7.7k ft. About a third of the trees in the forest are considered "old growth". The forest was used as a filming location for the 1952 movie Bend of the River, now considered one of the great Westerns.
