New Mexico Territory Map 1857 Territorial Print - Santa Fe, Tucson, Albuquerque

Henry Darwin Rogers and Alexander Keith Johnston issued this Territory of New Mexico sheet in 1857, published in London by Edward Stanford and engraved by W. & A.K. Johnston of Edinburgh, part of their Atlas of the United States. This printing marks proposed Pacific Railway routes in purple across a territory that, in 1857, still encompassed the land that would later become Arizona, five years before the two were formally split. The sheet maps the full New Mexico Territory, showing rivers, mountain ranges, settlements, and forts across a vast, still largely unorganized Southwest.

The Rio Grande runs the length of the sheet, the dominant waterway around which most of the territory's settlement had concentrated by the 1850s. Mountain ranges and plateaus are shown with topographical shading across the territory, capturing the rugged terrain of both present-day New Mexico and Arizona under a single boundary. Settlements and forts are marked across the map, sparse outposts reflecting how thinly populated the territory remained outside its river valleys. Together the Rio Grande, the mountains, and the scattered forts sketch a territory still years from the population growth or political split that would eventually divide it in two.

For a New Mexico or Arizona family with territorial-era roots, or a collector drawn to this British-published perspective on the pre-split Southwest, this sheet has a specific pull. The store also carries Arizona and New Mexico combined in Mitchell's later 1882 sheet elsewhere in this collection, and separately from Cram's 1893 and 1883 editions; this 1857 Rogers and Johnston sheet is the only one in the store to map the two as a single, still-undivided territory. It's printed unframed and available in a range of sizes to fit whatever wall it's headed for.
