Mount Adolph Knopf

Mount Adolph Knopf is a 6200. ft glaciated mountain summit located in the Boundary Ranges of the Coast Mountains, in the U.S. state of Alaska. It is situated 28 mi north-northwest of Juneau to the western side of the Juneau Icefield, on land managed by Tongass National Forest. Topographic relief is significant as the summit rises 2,200 feet (670 m) above the Eagle Glacier in 0.5 mi and 3,800 feet (1,158 m) above the Thiel Glacier in 1.25 mi. Precipitation runoff from the mountain's slopes drains to Lynn Canal.

Climate
Based on the Köppen climate classification, Mount Adolph Knopf is located in a subpolar oceanic climate zone, with long, cold, wet winters, and cool summers. Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (orographic lift), causing them to drop their moisture in the form of rain or snowfall. As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall. Winter temperatures can drop below 0 °F with wind chill factors below −10 °F. This climate supports the Eagle and Thiel glaciers surrounding the peak.

History
Mount Adolph Knopf's toponym and present location was officially adopted in 1976 by the U.S. Board on Geographic Names to honor Adolph Knopf (1882–1966), American geologist with the U.S. Geological Survey who performed pioneering geologic studies in southeast Alaska in 1909–1910. "Adolph Knopf Mountain" was originally applied in 1968 to the mountain that is now known as Mount Ernest Gruening. The "Adolph Knopf Mountain" toponym was officially changed in 1976 by the U.S. Board on Geographic Names to honor Ernest Gruening, known as "the father of Alaska statehood", the Governor of the Alaska Territory from 1939 through 1953, and one of Alaska's inaugural pair of Senators when Alaska gained statehood in 1959. The Adolph Knopf toponym was concurrently moved to the present peak eight miles north of its previous location.
