Split Thumb
Split Thumb is a glaciated mountain summit located in the Boundary Ranges of the Coast Mountains, in the U.S. state of Alaska. The peak is situated near the southern periphery of the Juneau Icefield, northeast of Juneau, 2.15 mi southeast of Nugget Mountain, and east of Heintzleman Ridge, on land managed by Tongass National Forest. Split Thumb is surrounded by the Lemon Creek Glacier to the west, and Norris Glacier to east. The Split Thumb Icefall is set on the east aspect of the peak. This peak's descriptive name was published in 1951 by the U.S. Geological Survey. 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.
