Grizzly Peak is a high and prominent mountain summit of the Collegiate Peaks in the Sawatch Range of the Rocky Mountains of North America. The 13,995-foot (4265.6 m) thirteener is located 2.6 miles (4.2 km) south-southwest (bearing 202°) of Independence Pass, Colorado, United States, on the Continental Divide separating San Isabel National Forest and Chaffee County from White River National Forest and Pitkin County.[2][3][1]

Elevation[edit]

Grizzly Peak is the highest summit in the United States less than 14,000 feet (4,267.2 m), making it the highest thirteener in the country. At one time, the peak's elevation was measured to be over 14,000 feet and was believed to be a fourteener, but more recent and accurate surveys have dropped it below that threshold.

Geology[edit]

The mountain is composed of andesite lava flows and breccias of Oligocene age.[4]
