Mount Jarvis is an erodedshield volcano andstratovolcano in theWrangell Mountains of easternAlaska. It is located inWrangell-Saint Elias National Park about 10 miles (16 km) east of the summit ofMount Wrangell. The mountain sits at the northeastern edge of the massive ice-covered shield of Wrangell, rising nearly 5,000 feet (1,500 m) above it in a spectacular series of cliffs andicefalls.
When seen from above, Mount Jarvis is distinctlydumbbell-shaped, with two prominent peaks connected by a narrower ridge. The mountain's main summit is 13,421 feet (4,091 m), making it one of numerousthirteeners (peaks between 13,000 and 13,999 feet in elevation) in Alaska. The second summit is located about 3 miles (5 km) to the north-northwest, reaching 13,025 feet (3,970 m) with over 725 feet (221 m) of prominence above the connecting saddle,[4]thus qualifying it as an independent peak on the list of thirteeners as well. The entire summit area including both peaks and the ridge is covered inglacial ice. The steep, rocky eastern and western faces of Mount Jarvis formheadwalls above thecirques of theJacksina Glacier andCopper Glacier, which flow northward out of the Wrangell Mountains.
Mount Jarvis was named in 1903 by F. C. Schrader, aUSGS geologist, for Lt.David H. Jarvis of theU. S. Revenue Cutter Service,[2] who led theOverland Relief Expedition to aid a whaling fleet trapped inArctic Ocean ice offPoint Barrow in 1897–98.
