The National Park Service cooperative agreement
Terrain360’s Montana work is done under a cooperative agreement with the National Park Service. On July 6 and 7, 2026, it ran 8.3 miles of the Jefferson River by water to the Missouri headwaters, rode 9.3 miles of bike trail from Missouri Headwaters State Park through Three Forks, and walked the park itself: nine short routes, 4.2 miles, including the plaque quoting Jefferson’s instructions to Lewis.
2027
The agreement’s final season is planned for late May to July 4, 2027: the Missouri from Great Falls to Fort Peck, and at least 50 miles of the Marias River.
