National Park Mountain, Mountain summit in Yellowstone National Park, Wyoming, USA

National Park Mountain is a 7,553-foot (2,302 m) summit in Yellowstone National Park, Wyoming, rising above the confluence of the Firehole and Madison rivers just west of Madison Junction. The French Wikipedia gives 2,301 m and places it in Teton County, southwest of where the Firehole and Gibbon rivers form the Madison.

The mountain received its name during the 1870 Washburn-Langford-Doane Expedition, which marked a key moment in establishing Yellowstone National Park. This expedition played an important role in protecting the area.

The mountain stands at the confluence of the Firehole and Gibbon rivers, where the Madison River begins, just west of Madison Junction. The name comes from the 1870 Washburn-Langford-Doane Expedition, whose members camped nearby and proposed protecting the region; the idea led to Yellowstone becoming the world's first national park in 1872.

Hikers can reach the summit through multiple marked trails, with the main path starting near Madison Junction and requiring moderate climbing experience. Good footwear and plenty of water are important since the trail can be strenuous and exposed.

The mountain offers direct observation points for both hot springs and volcanic formations that characterize the Yellowstone landscape. This dual view shows how the geothermal activity and geology of the park are connected.
