Mullan Military Road Interpretive Trail Professional Guide
Detailed Trail Description from our Guidebook
"The Mullan Military Road Interpretive Trail is a short loop hike passing the spot where the historic Mullan Tree once stood. The US Army built a wagon road from Fort Benton, Montana, to Fort Walla Walla, Washington, between 1859 and 1862.
Lieutenant John Mullan and his crew built 30 miles of this road in 1861, changing the route and going north of Coeur d’Alene Lake. Lieutenant Mullan carved the date Fourth of July 1861 on a tree, commemorating their construction reaching the pass and inadvertently naming Fourth of July Summit."
