tripometry: Grand Teton National Park

Short Overview

Grand Teton National Park is named for Grand Teton, the tallest mountain in the Teton Range. The naming of the mountainsis attributed to early 19th-century French-speaking trappers—les trois tétons (the three teats) was later anglicized and shortened to Tetons. At 13,775 feet (4,199 m), Grand Teton abruptly rises more than 7,000 feet (2,100 m) above Jackson Hole, almost 850 feet (260 m) higher than Mount Owen, the second-highest summit in the range. The park has numerous lakes, including 15-mile-long (24 km) Jackson Lake as well as streams of varying length and the upper main stem of theSnake River. Though in a state of recession, a dozen small glaciers persist at the higher elevations near the highest peaks in the range. Some of the rocks in the park are the oldest found in any U.S. National Park and have been dated at nearly 2.7 billion years.
