Because of its enormity, shortly after 1918, the end of World War I, Shelter Rock was the most photographed rock in the entire United States. It was so well-known that there were stories told to children about the rock. One of the tales hinted that Billy the Kids treasures were hidden in Shelter Rock.(Submitted on October 22, 2025, by Ian Lefkowitz of New York, New York.)
