To learn about Grand Canyon rocks, visit the museum at Yavapai Observation Station. The interactive exhibits chronicle the geological history and composition of the Canyon as well as providing a spectacular view. Admission is Free!
Exhibits are devoted to geology, with the main exhibit out beyond the windows, in the panoramic view of the Canyon. A series of back lit panels use a combination of text, floor-to-ceiling visuals, and interactive lessons to explain the geologic forces that shaped the Canyon, and the human history that shaped what we know about it.
