Senate issue of one of the most important 19th century explorations of the American West. Fremont and his colleagues covered some 10,000 miles between the frontiers of the Missouri and the shores of the Pacific. The report made substantial contributions in the fields of surveying, topography, and natural history. Fremont's expedition party included such notable explorers as the German topographical surveyor Charles Preuss, the American guides L. Maxwell and Christopher Kit Carson and the celebrated botanist John Torrey. The lithograph plates in this report include illustrations of both the countryside and flora, as well as plates of fossil ferns and shells. Twenty-two plates, three lithographic maps (lacking two large folding maps), 693pp. Octavo, original blind stamped cloth.
