A Fine Adventure. Descending Hidden Canyon from the top makes for a pretty good day of downclimbing and rappelling. Hidden was ascended via technical climbing about the time that other people were figuring out that going DOWN canyons was actually pretty fun. Many hikers have tried climbing up the obstacles in Hidden, and it has been the scene of numerous broken legs and difficult extractions over the years. There are several difficult and dangerous climbing sections near the top.
In big snow years, Hidden could hold snow and ice until well into the spring. Caution is advised.
The Hidden Canyon Trail was blasted out of the rock in 1928. A year earlier, technical rock climbing came to Zion when W. H. Evans ascended the Great White Throne via the south face. He built a fire on the summit to prove his accomplishment, but did not return to the valley the next day. A rescue team was organized and found him several days later lying at the base of the upper cliffs, bruised and delirious. The rescue effort led to the discovery of Hidden Canyon.
