This map is intended only for research. It's precision is based on the Mullan Road route as drawn on the Cadastral survey maps created in the years 1861 through the early 1900's and where and when possible, feet-on-the-ground research. The accuracy of this route is affected by the attention of the surveyor, private land usage, and the constantly changing route of a variously used wagon road, mule train trail, and farm access road.
If you wish to drive the Mullan Road route, refer to the Driving Tours.
When traveling, always be aware of changing conditions, your ability to drive on remote, unpaved roads, and never enter private property without the owner's permission.
