Carte Generale Des Etats-Unis De L'Amerique avec les Plans des principales Villes...

Highly detailed coast-to-coast map of the United States, published by Eustache Herrison in Paris, engraved by J.B. Tardieu, with inset plans of Washington, Boston, Philadelphia, and New York.
Herrison's map provides an exceptionally detailed and up-to-date treatment of the Transmississippi West in the Years between Lewis & Clark and John Fremont. Preserved are many of the last great myths of the American West.
There are two Salt Lakes shown (Timanagos and Teguayo), each connected to the Pacific by a mythical river. The mythical mountain ranges which were then the domain of Jedidiah Smith and other American Fur Traders and adventurers have been removed, with Herrison preferring to leave the area devoid of topographical details, other than the rivers primarily reported by the Spanish.

Excellent post-Lewis & Clark cartography appears in District De La Colombie (Oregon Territory), including many Indian Tribes, accurate river placements, and a tracing of the Lewis & Clark route, from the headwaters of the Missouri River to the Columbia River and back, one of the few maps to trace the route. Several places along the Route are named, including Canoe Camp and Travellers, and the different routes taken on the return are also noted separately, as is a point of Observation on the Marie River.

Several early Forts and Trading Posts are also noted in the region explored by Lewis & Clark. Other Lewis & Clark notes appear in the Missouri River Valley. The Rocky Mountain configuration is based on Humboldt and Pike. A road system in the West from Santa Fe to the Salt Lake area is depicted, along with Missions. To the north of the Canadian border, there are numerous Factories and Houses shown for the Hudson Bay Company and the Northwest Company, providing a marvelous snapshot of the vibrant fur trading business in western Canada, then loosely affiliated with the east, but very much an open and independent region inhabited by intrepid adventurers and Indian Traders.

In Texas, the site abandoned by Champ D'Asile is noted, as is the Presidio and Texas Capital. Double wide Arkansas and the Spanish Land Districts of Howard, St. Louis, Laurence, and Arkansas are shown West of the Mississippi.
