How old is the canyon? How did it form? The new exhibits at Yavapai Observation Station answer these and other geology questions. Displays include three-dimensional models, powerful photographs, and exhibits which allow park visitors to see and understand the complicated geologic story of the area. The historic building, located one mile (1.6 km) east of Market Plaza, features expansive canyon views. The bookstore offers a variety of materials about the area. Open daily 8:00 a.m. to 5:00 p.m. Several ranger programs begin here.
