Elk Tooth sits 3/4 mile east of Ogalalla Peak on the border between Rocky Mountain National Park and the Indian Peaks Wilderness. This mountain dominates the view from the trail in the Middle St. Vrain Creek valley. Elk Tooth has a very steep south face, a 4-mile-long east ridge connecting it with St. Vrain Mountain, and a shorter but very rugged west ridge connecting it with Ogalalla Peak. A slender and obvious couloir on its east face also looks inviting.
