"[Lot of 2] Topographical Map of the Road from Missouri to Oregon Commencing at the Mouth of the Kansas in the Missouri River, and Ending at the Mouth of the Wallah Wallah in the Columbia ... Section I [and] Section II", Fremont/Preuss

This lot includes the first 2 sections (of 7) of the historic map that established the Oregon Trail Route. It was compiled by Charles Preuss during Fremont's controversial Third Expedition. Preuss created the seven-part map from Fremont's 1845 map along with additional topography based on Fremont's sketches and notes as well as his own expedition notes. Wheat calls this set a rarity that is important in the "evolution of the transcontinental wagon roads" and deserves "close study." Wheat devotes four pages to describe the map and illustrates all seven sheets in his monumental work.

These two sheets cover the eastern section of the "road" from the confluence of the Kansas/Missouri Rivers to beyond Cedar Bluffs on the North Fork of the Platte River. The sheets contain fascinating comments from Fremont's narrative, and notes regarding water, grass, fuel, game and Indians; invaluable information for emigrants at the time.
