Montana Territory Map 1887 Territorial Print - Helena, Butte, Miles City

The General Land Office published this map of Montana Territory in 1887, drawing on the most current government surveys available at the time to record the territory's rapidly expanding grid of townships, land districts and county seats. As the federal agency responsible for surveying, platting and selling public land across most of the American West, the General Land Office produced maps as working administrative tools rather than decorative atlas plates, and this sheet reflects that practical purpose in its careful key distinguishing Surveyor General offices, land offices, subdivided townships, county boundaries, railroads, military reservations and Indian reservations from one another. It captures Montana just three years before statehood, at a moment when its southern and eastern reaches remained only partially surveyed even as the territory's mining and railroad economy accelerated.

Helena anchors the map as territorial capital, while Butte appears as Montana's booming copper-mining center, already drawing the investment that would soon make it one of the largest cities in the Northern Rockies. Miles City marks the territory's expanding presence along the Yellowstone River in the east, a cattle and rail town growing up in the wake of the northern Plains wars. The map highlights, in gold, the proposed 1886 extension of the Northern Cheyenne Reservation, a live political question at the time of publication, and it candidly shows just how much of Montana, particularly its mountainous western reaches, remained unsurveyed and unmapped beyond the most basic watershed and topographic detail available to government cartographers.

This official government survey map makes a meaningful gift for a Montana family with roots in the territory's final years before statehood, or for a collector interested in General Land Office cartography as a category distinct from commercial atlas publishing. It offers a very different kind of document from the store's earlier Montana sheets by De Lacy and Lloyd, trading their decorative engraving for the plain, functional record-keeping of a working federal survey map. It is available unframed in a full range of sizes, from a compact print for a study to a large-format piece for an office or den.
