1956 Map of Marble Canyon

About this map

The Colorado River carves through a landscape of immense geological layers, flowing past the Grand Canyon National Park and beneath the historic Navajo Bridge. During the mid-1950s, this region was characterized by the intersection of traditional Navajo and Hopi territories with emerging industrial interests, most notably the Uranium mill near the border of Monument Valley. The map detail captures the remote trading post economy at sites like the Cow Springs Trading Post and Chilchinbito Trading Post, which served as vital crossroads for local residents long before modern infrastructure expanded.
