"No. 15 Map of Oregon and Upper California", Mitchell, Samuel Augustus

This is the smaller school atlas version of Mitchell's well-known map based largely on Fremont's map of 1845. It is the most desirable edition as it features the U.S. border with Canada at 54°40' with the notation "Boundary of 1824." Upper California extends eastward to the Rio Grande and Oregon Territory extends to the Continental Divide. Shows the Oregon Route (Oregon Trail) in good detail as it winds from the Sweetwater River through South Pass to Oregon City. Numerous Indian tribes and villages and forts are located. An early depiction of the Great Basin is here called the Great Interior Basin of California. At lower left is the inset "Map of the Columbia River from the Cascades to the Pacific Ocean" which locates Oregon City, Ft. Vancouver, a mission on the Columbia, Mt. Hood, and Mt. St. Helens with a height of 13,300 feet.
