This is a great example of pictorial bird's-eye-style maps that were used for advertising and publicity in the early part of the 20th century. This colorful perspective map covers the region serviced by the Union Pacific Railroad, from Salt Lake City (shown on the distant horizon) down to Boulder City, which appears to be larger than Las Vegas. It has a great depiction of Boulder Dam including a small portion of Black Canyon and shows water spraying from the turbine generator outlets. Steamships (!) are shown in Lake Mead. The map also includes the Grand Canyon, the National Parks of Bryce and Zion, Cedar Breaks Nat. Monument, and more. The route of Union Pacific Tours is shown along the north rim of the Grand Canyon where the Union Pacific Grand Canyon Lodge is prominently located. This striking image was drawn by Gerald A. Eddy of Los Angeles and published by the Boulder Dam Service Bureau, Boulder City. Blank verso.
