Ac ko mok ki (the Feathers), mapmaker
Copied by Peter Fidler
February 7, 1801

Ac ko mok ki, a Blackfoot Indian chief, drew this map for Peter Fidler, postmaster and surveyor for the Hudson's Bay Company, 1788 1822. Because Ac ko mok ki probably sketched the original map on the ground or in the snow, Fidler carefully copied and annotated this information into his notebook, which is reproduced here. Oriented with west at the top, this map detailed for the first time the drainage network of the Missouri River and provided new information about the location and width of the Rocky Mountains (seen at the top of the map as a double-lined feature) and the Indian tribes living in the area. Ac ko mok ki surveyed and described to Fidler the adjacent plains for a distance of some 500 miles. His information depicted areas theretofore not explored by Europeans.
