A British published map of the US West that is indebted to Fremont and his great map of this area published just a few years prior. With clarity and simplicity it illustrates the major mountains and rivers along with the forts and cities. Spans from the front range of the Rockies, and the plains of present day Montana to the Pacific Coast. An interesting notation occurs just off the mouth of the Columbia River where it states, “The Navigation of the Columbia River is free to all British Subjects”.
