The Tetons

“The grand lift of the Tetons is...a primal gesture of the earth beneath a greater sky”
— Ansel Adams
Movement along the 40-mile long Teton fault began between six and nine million years ago, uplifting the mountain range with each earthquake two to three feet while dropping the valley floor (Jackson Hole) four to six feet. This also means they rise abruptly from the valley floor without foothills, making them even more prominent. The Tetons are the youngest range in the Rocky Mountains - most of the rest of the Rockies are between 50 and 80 million years old. Because the mountains are so young, erosion has not had a chance to weather and round them, so they are still jagged. Additionally, they have been extensively glacially sculpted over the past 200,000 years, creating U-shaped canyons, gouging out depressions that have become lakes, and sharpening peaks. (Most of this information is from the NPS website).
Technically, they should be in the Rockies section, but I felt this dramatic mountain range deserved a separate section.
