A loop marks the end of Park Road 5 and the conclusion of the scenic drive. Located in this area are a number of fine camping areas, picnic grounds, the old stone cottages called the “Cow Cabins,” and rest rooms with shower facilities (fig. 36). [Illustration: Fig. 32. The “dome” on Capitol Peak is a well-known canyon landmark. Composed of the Tecovas and Quartermaster Formations, the profile of Capitol Peak is referred to as the Sleeping Indian. (The “Indian’s” head can be seen in the right background.)] [Illustration: Fig. 33. Fortress Cliff is a prominent feature on the eastern rim of the canyon. Seen here are the precipitous cliffs developed in the Ogallala caliche (p. 26) and the sandstones and shales of the Trujillo Formation.] [Illustration: Fig. 34. The Rock Garden is a jumbled mass of Trujillo sandstone boulders that mark the site of an ancient landslide.] _Hiking._— There are a number of established trails for the visitor who is interested in hiking. The more popular trails include those to the Spanish Skirts and Catarina Cave (p. 37), the Devil’s Tombstone, the Lighthouse (p. 39), and the Devil’s Slide (p. 40). Park rangers will be glad to provide more complete information about these and other trails within the canyon. _Horseback riding._— Saddle horses can be rented at the stables located east of the road near the Pioneer Amphitheatre. There are a number of trail rides that can be taken on well-trained horses accustomed to the rugged terrain of the canyon. Additional information may be obtained from the attendants at the stable. _Camping and picnicking._— An ample number of well-developed camping and picnic areas are scattered throughout the canyon. Most are located adjacent to or a short distance from Park Road 5; they are equipped with outdoor fireplaces and tables. Running water, rest rooms, and showers are provided in certain areas. Campsites are available on a first-come first-served basis, and there is a 10-day limit on overnight camping. Detailed information on camping regulations and camping areas is available from a park ranger or at the Entrance Station. _Photography._— Palo Duro Canyon offers many opportunities for both amateur and professional photography. The multi-colored rock formations, erosional land-forms, and plants and animals offer limitless possibilities to the creative and imaginative photographer. Color shots are especially effective, but a haze filter will be helpful when photographing distant objects. Morning and afternoon are the best times for picture taking as the mid-day sun is “flat” and lends little perspective to the canyon scene. [Illustration: Fig. 35. The Devil’s Slide in the south end of the park is an eroded spur of Tecovas shales. Some of the “slides” made by visitors are indicated by the arrow.]
