HOOD, MOUNT, a peak of the Cascade range in Clackamas and Hood River counties, Oregon, about 5o m. E. of Portland. It is an extinct volcanic cone of great symmetrical beauty rising to a height of 11,253 ft. above sea-level, the highest point in the State. The peak was built upon the comparatively level back of the range, which is about 4,000 ft., by successive volcanic erup tions. The summit is a part of the rim of the ancient crater ; steam jets and fumaroles still exist about Crater Rock. Its crest, clad in perpetual ice and snow, gives rise to eight glaciers which extend down its sides to an elevation of about 6,000 ft. above the sea. Mt. Hood was first discovered in 1792 by a member of Van couver's exploring expedition and was named in honour of Rear Admiral Samuel Hood of the British admiralty. The first suc cessful ascent was made on Aug. 4, 1854, from the south side, by a party under Captain Barlow, builder of the pioneer road to Oregon. It is now more frequently climbed than any other snow peak in America.
