Place/Date: Baltimore / 1848
Title: Map of Oregon and Upper California from the surveys of John Charles Fremont and others authorities drawn by Charles Preuss…1848

Condition Rating


Fremont’s landmark map of the West, focusing on California, Arizona, Utah, and Nevada.

The present issue of the map, which was originally published with Frémont’s Geographical Memoir Upon Upper California, came with California Messages and Correspondence, House Ex. Doc. 17, 31st Congress, 1st Session, 1850, and is smaller than the original issue, being confined to the California and Great Basin portions, but is on the same scale. Wheat notes that this issue “more fully renders Fremont’s routes of 1846 in the Central Valley than do the original issues of 1848 and 1849.”


Charles Preuss

George Karl Ludwig Preuss (1803–1854), anglicized as Charles Preuss, was a surveyor and cartographer who accompanied John C. Fremont on three of his five exploratory expeditions of the American west, including the expedition where he and Fremont were the first to record seeing Lake Tahoe from a mountaintop vantage point as they traversed what is now Carson Pass in February 1844.

John C. Frémont

John Charles Frémont or Fremont (January 21, 1813 – July 13, 1890) was an American explorer, politician, and soldier who, in 1856, became the first candidate of the Republican Party for the office of President of the United States. During the 1840s, when he led five expeditions into the American West, that era’s penny press and admiring historians accorded Frémont the sobriquet The Pathfinder.

During the Mexican–American War, Frémont, a major in the U.S. Army, took control of California from the California Republic in 1846.
