Black Mountain is a prominent 5,891 foot (1,796 meter) mountain summit located in the Alsek Ranges of the Saint Elias Mountains, in southeast Alaska.[4] The mountain is situated in Glacier Bay National Park and Preserve, 750NaN0 northwest of Juneau, between the Riggs and McBride glaciers. The months May through June offer the most favorable weather for viewing or climbing Black Mountain. Weather permitting, Black Mountain can be seen from Muir Inlet of Glacier Bay, which is a popular destination for cruise ships.
Based on the Köppen climate classification, Black Mountain has a subarctic climate with cold, snowy winters, and cool summers.[5] Weather systems coming off the Gulf of Alaska are forced upwards by the Saint Elias Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. Temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports the Riggs Glacier below the west slopes, and McBride Glacier to the east.
