California, Oregon, Washington, Utah and New Mexico in 1859 - Sacramento, Portland, Olympia, Salt Lake City, Santa Fe

Philadelphia publisher Charles Desilver issued this map of California and the Territories of Oregon, Washington, Utah, and New Mexico in 1859, a document capturing the American West at a moment of extraordinarily rapid territorial reorganization and new mineral discovery. Its most striking feature is the map's early acknowledgment of gold discovered along the South Fork of the Platte River near Cherry Creek, labeled directly on the sheet as a "Gold Region," recording the find that would soon draw thousands of prospectors to the land that became Colorado Territory two years later. The map also marks the first attempt at drawing modern county boundaries across the soon-to-be territories of Nevada and Arizona, replacing the simple horizontal county divisions earlier maps had used across Utah and New Mexico, while newly created counties east of the Cascades in Washington and Oregon, including Skamania, Walla Walla, and Wascopen, appear for the first time on a Desilver map.

The map traces John Fremont's and Stephen Kearny's exploration routes alongside the older Spanish or Los Angeles Route, the Oregon Trail, and the Lewis and Clark canoe routes, a layered record of decades of western exploration compressed onto a single sheet. Along the disputed border east of Tucson, both "Bartlett's Line" and "Graham's Line" are shown, the same competing boundary proposals stemming from the 1848 Treaty of Guadalupe Hidalgo that the 1853 Gadsden Purchase had only recently settled. The gold strike near Cherry Creek that this map records so early on came from a modest 1858 discovery by a party of Georgia prospectors led by Green Russell, followed in 1859 by the far larger rush that became known as the Pike's Peak Gold Rush, drawing thousands of "Fifty-Niners" to towns including the newly founded Denver and Boulder even though the actual gold lay some eighty-five miles north of Pike's Peak itself.

This map is a compelling gift for a Colorado, California, or Southwestern family with roots in the gold rush and territorial settlement era, someone drawn to Denver and Boulder's founding years specifically, or a collector interested in the rapid county-by-county reorganization of the American West between 1850 and 1861. It stands alone among the Vault's Western regional offerings for its early, direct labeling of the gold discovery that would soon create Colorado Territory. It's available unframed in a full range of sizes, from a compact study print to a larger statement piece.
