Triple Divide Peak (Montana)

Triple Divide Peak is a mountain in northwestern Montana that is commonly identified as a continental hydrological apex for North America. Water falling on different flanks of the peak enters river systems that reach the Pacific Ocean, the Atlantic Ocean via the Gulf of Mexico, and the Arctic Ocean via Hudson Bay.

The summit rises to about 8,020 feet (approximately 2,445 meters) and is located on or very near the Continental Divide within the Lewis Range. Hikers reach the area by backcountry trails in the surrounding national park and wilderness lands.

The peak’s significance derives from its hydrological position rather than built history; it has been noted in geographic and hydrological literature for its triple drainage pattern. It lies within the mountainous terrain of northwest Montana and is part of the broader headwaters country of several major North American river systems.

Triple Divide Peak is located in the Lewis Range of northwest Montana, within federally managed park and wilderness areas. It is accessible only by trail and sits among rugged alpine terrain.

• Elevation and hydrology: 8,020 feet (about 2,445 meters); commonly cited as North America's hydrological apex where drainage flows to the Pacific, Atlantic via the Gulf of Mexico, and the Arctic via Hudson Bay.
