From Devils Tower in northwestern Wyoming, Host David Horton and Clay Jenkinson discuss Theodore Roosevelt's conservation achievements. When the National Monuments and Antiquities Act was passed in 1906, President Roosevelt lost no time in setting aside what would become 18 National Monuments, starting with Devils Tower just west of the Black Hills. Roosevelt had little to do with the creation of the Antiquities Act, but he made the most of it, culminating in his colossal designation of Grand Canyon National Monument in 1908. In the course of his two-term presidency, Roosevelt set aside a whopping 230 million acres of National Park, National Forest, National Monument, National Wildlife Refuge, and National Game Preserve. No president has done more. David asked Clay to outline his three-phase Roosevelt conservation tour for 2026. First, South Dakota, Wyoming, and Colorado; later, Montana and Idaho; and in the fall, all of Roosevelt's conservation designations in the Four Corners region of the Southwest.
