Seen above is Mount Jefferson (3,199 m, 10,495 ft) one of 13 Cascade volcanoes and, after Mount Hood, the second tallest in Oregon. The volcano received its present name in 1806 when Lewis and Clark named it for the U.S. President. There's possible evidence of an eruption of Mount Jefferson around 1,000 years ago; however, the last verifiable eruption was during the late Pleistocene. Jefferson is a stratovolcano showing considerable glacial erosion. The photo was taken on October 24, 2017, a rare clear day just west of Warm Springs. The dryness of the landscape shown here is indicative of the Oregon rain shadow in this high desert country rather than of prolonged drought.
