Glen Canyon Revealed
A living archive of history, photography, maps, journals, and analysis exploring Glen Canyon and the Colorado River system.
An Archive of Changing Landscapes
Before it was submerged under Lake Powell in 1963, Glen Canyon was one of the most spectacular, ecologically diverse, and culturally significant canyon systems on the Colorado River. This website serves as a permanent scholarly repository—a digital home for the maps, logs, and photographs that document what was lost, what remains, and how the river system continues to evolve today.
Here you will find a curated archive containing historical maps from early survey expeditions, pre-dam photography, decades of personal field journals, detailed geographic logs of Lake Powell's changing levels, and objective analyses of Colorado River hydrology and water management policies.
