This map was issued to meet the huge demand for information concerning the gold deposits in California and was published in J. Quinn Thornton's Oregon and California in 1848. According to Wheat, it is a combination of 1848 maps by Fremont and Tanner one year prior to statehood. It covers the western United States from Independence, Missouri to the Pacific Ocean. Several overland trails are depicted including the Oregon Trail, Fremont's route and Kearney's route. Numerous Indian tribes are located and a table at top indicates the distances from New York and Panama to points west. Published by Harper & Brothers in New York.
