In 1933, during the Great Depression, President Franklin D. Roosevelt established the Civilian Conservation Corps (CCC) providing employment for young, unmarried men. From 1934–41, at Bryce Canyon National Park the CCC planted trees and shrubs, built and improved roads and trails, developed campgrounds, paved parking lots, and provided insect control. At Rainbow Point, they built the overlook structure and the Under-the-Rim Trail. Their hard work created many improvements—a lasting legacy—enjoyed by visitors today.
