Explorers Column, Cañon de Chelle, Arizona. This shaft is the work of nature, and is about 900 feet in height; base about 70 by 110 feet. It stands near the center of the Cañon, and it is almost impossible to believe that it is not the work of human hands, No. 23 from the series "Geographical Explorations and Surveys West of the 100th Meridian"
