This is the first GLO map produced of Wyoming. It was compiled from the official records of the General Land Office and other sources by C. Roeser. It depicts watershed, railroads, and early place names including Reno, Kearny, Laramie and Fetterman forts, Camp Brown, Old Camp Brown, St. Mary's Station on the Oregon Trail, Miners Delight and much more. The legend further locates County Seats, Military Reservations and Indian Reservations. The Union Pacific Railroad's 20 Mile limit cuts a wide path through the southern part of the territory. Yellowstone National Park is clearly shown. Most of the territory is largely unsurveyed in this first edition.

The General Land Office produced this map as part of a series of maps of the States and Territories to celebrate the Centennial. They were recognized as the most accurate and detailed maps of their time, and subsequently were widely used by commercial mapmakers.
