Thor Peak is in the northern Teton Range, Grand Teton National Park, Wyoming. Mount Moran is one mile (1.6 km) to the east. The summit is the eighth highest in the Teton Range. While the easiest route up the mountain, the south slope, is only rated a class 4, the mountain's remoteness and difficulty of approach makes it a challenging mountain to summit. Several semi permanent snowfields as well as the Triple Glaciers are located on the east and northern slopes of the mountain.
