Major Valley: Bow
Visible from Highway: 1
Ascent Party: Samuel E.S. Allen
Named by: Samuel E.S. Allen
Named for: This minor high point was thought to resemble a thumb.
From some angles this is quite a prominent feature, although of modest elevation and the 1:50,000 maps show no closed contours at this point that is the end of the east ridge of Mount Whyte. It caught the eye of Samuel Allen in 1891 who wrote that he saw, "a towering aiguille, absolutely vertical from the lake." He described his ascent as follows: "In the hope of turning it in flank or rear I ascended the ledge of that peculiar mountain locally known as "The Beehive" to the top of the latter, whence I was able, by following the narrower ledges, to turn a corner and reach a wider gorge, choked by a vast boulder, upon which the remainder of its accomaying avalanche had come to rest. I could reach a portion of it, but, not knowing how securely it was wedged, hesitated to experiment with it. I finally passed the place and made the pinnacle."
