An attractive six-sheet map of the United States with incredible detail throughout. Filled with place names, watersheds and mountains precisely delineated in hachure. Details include the recently completed Pacific Railroad, the newly created Yellowstone National Park, and numerous routes and trails identified in the West. Engraved on steel with fancy titling and keyboard-style borders. If joined, the full map would measure approximately 48 x 26.5".
