Split Thumb is a 5,523 ft (1,680 m) glaciated mountain summit located in the

U.S. Geological Survey.[4] The first ascent of Split Thumb was made July 2, 1954, by a Juneau Icefield Research Project party comprising Edward LaChapelle, Dick Hubley, Carlton Ray, Dr. Conrad Buettner, and Bob Goodwin.[6]

Climate

Based on the Köppen climate classification, Split Thumb is located in a subarctic climate zone, with long, cold, snowy winters, and cool summers.[7] Weather systems coming off the Gulf of Alaska are forced upwards by the Coast Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. Winter temperatures can drop below 0 °F with wind chill factors below −10 °F. The month of July offers the most favorable weather to view or climb Split Thumb.
