In 1842 and again in 1843-1844, John C. Frémont led expeditions
to survey the route of the Oregon Trail from the Missouri River
to the Columbia River. On his return in 1844, Frémont traveled
into Mexican-held California and then headed east completing a
6,500-mile circuit of the West. Charles Preuss, the expedition's
cartographer, prepared this map, depicting only geographic information
collected during the expedition. Originally published with Frémont's
1845 report, the map was the first reliable depiction of the emigrants'
route through the West since it was based on scientific measurements
of latitude and longitude.
