A very interesting map depicts the region with the largest extents of Utah and New Mexico territories. Utah Territory encompasses all of today's Nevada and extends west to the Continental Divide into present-day northern Colorado with Fillmore City as its capital. New Mexico Territory includes part of southern Colorado and stretches west to include Arizona and the southern tip of present-day Nevada . Fremont's routes, proposed routes for the Pacific Railroad, the Spanish Trail, and much more are located. Kanzas is to the east. Dated 1855 but it was published circa 1857. Professionally encapsulated in archival Mylar.
