The document is a presentation about Colorado National Monument. It discusses the geological formation of the monument, which began with the deposition of sedimentary rocks as mountains eroded over millions of years. Layer upon layer was deposited, forming thick formations like the Kayenta and Wingate formations visible today. Diagrams and photos show the distinctive canyon landscapes carved by erosion over time, exposing remnants of the older rock layers that now form cliffs, walls, and other geological features in the monument.
