"A Map of the Sources of the Colorado & Big Salt Lake, Platte, Yellow-Stone, Muscle-Shell, Missouri, & Salmon & Snake Rivers, branches of the Columbia River", Bonneville, Benjamin L. E. de

Important map of the region of the present-day intersection of Idaho, Montana, Wyoming and Utah. Wheat considered the map the best representation of the region during this period. It shows the headwaters of the Wind, Sweetwater, Green (Colorado of the West), Snake, and Salmon Rivers relatively accurately. The course of the Bear River to Lake Bonneville (Salt Lake), the Three Tetons and the 3 Buttes east of the Great Lava Plain are well placed.
