Teewinot Mountain
Teewinot Mountain is the sixth highest peak in the Teton Range, Grand Teton National Park, Wyoming. The name, originally spelled Tee-Win-At, is an Indian word meaning "pinnacles", which is appropriate since the summit is actually a large monolith with several sharp summit spires, the highest of which is quite exposed and big enough for only one or two people. The most common route to the summit is via the ramps and gullies of the East Face, which rises 5,600 ft directly above Lupine Meadows. The long Teton Range is the youngest mountain chain in the Rocky Mountains, and began their uplift 9 million years ago, during the Miocene. Several periods of glaciation have carved Teewinot Mountain and the other peaks of the range into their current shapes. Broken Falls is one of the tallest cascades in Grand Teton National Park and descends down the eastern slopes of Teewinot Mountain.
