Bunsen Peak

Bunsen Peak is a mountain summit in Yellowstone at an elevation of 8,564 feet that rises sharply above Mammoth Hot Springs. It has steep slopes with exposed rock and offers unobstructed views from the top toward the Gardner River valley and neighboring peaks.

Ferdinand Hayden and Captain John Barlow completed the first documented climb of the mountain in 1871. This early expedition contributed to the scientific exploration and mapping of the Yellowstone region.

The peak was named in 1872 after German chemist Robert Bunsen, who studied the geology of volcanic geysers. From the summit, visitors can look down on the hot springs below and understand why this scientist gave his name to the location.

The route to the summit starts south of Mammoth and goes about 2.1 miles uphill through varied terrain. Sturdy footwear and some scrambling experience help, as the trail can be exposed and slippery in wet weather.

The mountain is a cinder cone, a rare volcanic landform that stands apart from other peaks in the area. The geology of this cone allows visitors to see volcanic processes directly displayed in the landscape.
