Mount Sanford is a shield volcano in the Wrangell Mountains in Alaska . At 4949  m , it is the second highest peak in the mountain range and the third highest volcano in the United States . To the south, the volcano has one of the steepest slopes in North America with a gradient of 2,400  m over a distance of 1.6 km .

geology

Mount Sanford is mainly composed of andesite . It is an ancient volcano from the Pleistocene , with the upper parts near the summit probably not forming until the later Holocene . 900,000 years ago the volcano was formed on three smaller shield volcanoes. Notable events in the history of Mount Sanford include a large lava flow that flowed down the northeast slope and a smaller eruption at a crevice that also caused a lava flow. Radiometric measurements indicated that the latter took place around 320,000 years ago.

history

In 1885 Henry T. Allen named the volcano after the Sanford family. Some of his ancestors bore this name.

Mount Sanford was first climbed on July 21, 1938 by the well-known mountaineers Terris Moore and Bradford Washburn . Their chosen route over the Sheep Glacier ( Sheep Glacier ) from the north is still the normal route to the summit. The Japanese Naomi Uemura climbed it alone for the first time on September 19, 1968. He died in 1984 trying to climb Denali alone.

On March 12, 1948, a Douglas DC-4 of Northwest Airlines crashed at Mount Sanford. None of the 24 passengers and six crew members survived the crash. Snow covered the wreck within a short time. It was only found in 1999.
