1. Coal: Black Wave of the Future Marker
Inscription. President Jefferson told Lewis to record mineral resources of every kind; but more particularly metals, limestone, pit coal, & saltpeter. At that time, Jefferson considered coal the basic natural resource of the future. Today, eastern Montana has one of the largest coal reserves in the country and has been able to establish a relatively modest, but stable, coal industry that has survived for a number of years. Watch for its black seams as you travel along the Yellowstone River.

"below this river on the Stard Side (right side) at a few Miles from the Rochejhone the hills are high and ruged Containing Coal in great quantities. - William Clark, July 29, 1806
