The first ascent of The Moose's Tooth was in June, 1964, by four Germans, via the Northwest Ridge. In June, 1974, Gary Bocarde, Michael Clark, Charles Porter, and John Svenson climbed the lower Southwest Summit via the Southwest Face, for the second ascent of the massif, though not of the main summit. They found a great quantity of rotten rock. In July, 1975, Jon Krakauer, Thomas Davies, and Nate Zinsser made the second ascent of the main summit, via a couloir on the south face which they called the Ham and Eggs Route. This is the most popular route on the mountain today.
