The vast 1 million acres of Cedar Mesa are filled with thousands of miles of canyons, most of which are below the flat tableland of the mesa. Hidden in these canyons are thousands of Puebloan ruins and artifacts, new discoveries of which are still being made by hikers today. Many sites were also discovered by the many prospectors looking for gold, uranium, and other valuable minerals. One such prospector, Cass Hite, was exploring White Canyon in 1883 looking for gold when he found a treasure of a different sort, three magnificent natural bridges, some of the largest in the world.
