Washington Hood's Map of Western Territory.
Important early map of Indian Territory and the first map by Washington Hood, which accompanied Horace Everett's Regulating The Indian Department...
The map extends from Santa Fe, New Mexico and the Yellowstone River in the west, to the Mississippi River, Ft. Smith and Ft. Towson, focuing on the regions occupied by the Indians relocated from the east.
Everett's important report on the Indians and the conditions in the country west of the Missouri, accompanied three House Bills to provide for the organization of the Dept. of Indian Affairs. Wheat described as a highly credible performance, showing the country north of the Red River to Nebraska, and west from the Ozarks to Santa Fe.
Wheat comments that the map "not only showed the various Indian Land assignments, by tribes, west of the Arkansas and Missouri, following McCoy, but its maker used Brown's Santa Fe trail material, and delineated the country to the front wall of the Rockies and Santa Fe with considerable accuracy. The Black Hills run almost north and south. One curious point is that only the Spanish Peaks and "Larimer's" (Laramie) Peak (near the North Fork of the Platte) are shown in the mountains. It is supposed that Isaac McCoy assisted in the making of this map. He had offered advice to Humphrey Phelps and his manuscript map that has been described apparently had consideable "influence."
