This scarce, large-scale map covers western Montana, Idaho and part of Wyoming. It features Lewis and Clark's route with notations concerning the hardships they encountered on the passage. John Colter's 1807 route through Crow country is also shown. The map is based on the Lewis and Clark map as evidenced by the erroneous Lake Riddle draining into the Big Horn River. Several Indian tribes are located (along with their population) but there are no towns or settlements shown. The source of the Yellowstone River is noted as chaude et sulfurease (hot and sulfurous).

The Atlas Universel was the first atlas to present all the maps on the same scale (1: 1,641,836), with each map covering an area of approximately 20 degrees longitude (from Paris) and 6 degrees of latitude. Also considered to be the first lithographic atlas ever published. There was only one edition, published in 1825-27, and the subscription list shows that 810 copies were sold.
