Discover Montana's History by Theme
Montana has thousands of roadside markers. We group them into 15 thematic collections (Lewis & Clark, mining, railroads, and more) so you can explore related stories. These lists are not a single driveable highway route: markers were placed where topics happened, and many only mention the theme in passing. The map line connects stops for browsing—it does not follow one road.
Lewis and Clark National Historic Trail

Old North Trail
Explore markers that reference the Old North Trail—the ancient north–south travel corridor along the Rocky Mountain front used by Indigenous nations and later described by travelers and scholars. Coverage in this guide follows markers that name the trail explicitly; more front-range sites can be added over time.
Mullan Military Road
Follow the path of Lieutenant John Mullan’s 1860s military wagon road—the first all-weather wagon road across the Rockies in the northern U.S.—through western and southwestern Montana. Markers tie Mullan’s survey and construction to today’s passes, rivers, and towns.
Yellowstone Trail (auto trail)

Visit Montana sites associated with the Nez Perce War of 1877 and the federally designated Nez Perce (Nee-Me-Poo) National Historic Trail—from the Bitterroot to the Bear Paw Mountains.
