Geographical Memoir Upon Upper California, in Illustration of his Map of Oregon and California

Geographical Memoir Upon Upper California, in Illustration of his Map of Oregon and California. By John Charles Fremont. Addressed to the Senate of the United States. Washington. Wendell and Van Benthuysen, Printers. 1848. 67 pp. map. (Sen. Misc. doc. no. 148, Serial 511. 30th Congress. 1st Session.)

It is the large Charles Preuss map that makes this document valuable.

(82.5X65.5 cm) Some bibliographers cite it as the most significant map of 1848, and especially so since its publication coincided with the gold strike in California. The map and the geographical memoir are significant in another respect in that Fremont's journals of his 3rd expedition, 1845-46, were burned; and this report and map represent the most immediate print connec tion to that expedition. Fremont: "The part of the map which exhibits Oregon is chiefly copied from the works of others, but not entirely... my own explorations in that country. nearly two thousand miles."

The topographer with Fremont on his 3rd expedition was Edward Kern, and it has been claimed that his notes were used in Press's preparation of the 1848 map.

Several tears along folds one reparied edge to neat. otherwise a very clean and nice example of this historic map.
