Showing the entirety of the Oregon Territory and a good portion of the West, this map was produced by a cerographic process that was developed by Morse & Breese. Now an uncommon map to come across, this spans roughly from southern Wyoming, up to the present Canadian border, and west to the Pacific. Notes a lot for tribal locations, as well as numerous Missionary posts, rivers, major topography, as well as a few interesting notations such as “Oil Spring”, which would be someplace in between Thermopolis and Gilette, in present day Wyoming.
