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