Northwest of Squaw Creek Picnic Area the road passes along the edge of the breaks overlooking the river to a junction with CEDAR CANYON HORSE TRAIL at =5.8 m.= Left on this 5-mile trail, which is very similar in character to the Chaloner Creek Horse Trail, are lookout points affording excellent views. In spring portions of the trail show a profusion of wild flowers. The highway proceeds NW. to the junction with a graded road. Right at this junction on a road disclosing very good views; it leads NW. along the west side of dry SQUAW CREEK to the northern boundary of the park, =6 m.= Beyond lies ARNEGARD, =20 m.= (_see Tour 4_), by which the Badlands and the park can be entered from the N. At =7 m.= is CEDAR CANYON LOOKOUT, which commands an exceptionally good view to the S. across the Little Missouri River and beyond, where as far as the eye can reach stretch the tumbled outlines of the buttes. Northwest of Cedar Canyon the road moves out upon the plateau above the Badlands and then turns W. and SW. in a large arc along the edge of the breaks to SPERATI POINT, =14 m.= (_see Tour 10_), a high shoulder of the plateau, overlooking the spectacular GRAND CANYON OF THE LITTLE MISSOURI. Lying just W. of the bend of the Little Missouri where it turns E. toward the Missouri, the point affords views up and down the canyon, which in places is 600 ft. deep. It is proposed to make this a completely developed recreational center, with cabins, stables, lodge, and a store. From Sperati Point an unmarked and indefinite trail, which should not be tried without a guide, leads SW. Left on this trail to a PETRIFIED FOREST, =2 m.=, one of those Badlands areas, often many acres in extent, which abound with petrified logs and stumps. Petrified stumps are a common sight throughout the valley of the Little Missouri, suggesting that at one time it must have been heavily forested. When the originals of these stone trees died, their trunks, either standing or fallen, soaked up soil water holding mineral matter in solution. As the water evaporated, the mineral matter was left behind, filling the pores of the wood and the tiny cavities produced by decomposition. In time decay removed all the wood and the trees became stone, or, popularly, petrified wood. Some of the logs--for, of course, the trees are not now standing--are as much as 35 ft. in length and 2 ft. in diameter. In some places the soil has been washed and blown away from beneath the stumps, leaving odd formations shaped like toadstools. SOUTH ROOSEVELT REGIONAL STATE PARK TOUR East entrance (_see Tour 8_)--Hell's Hole--West entrance (_see Tour 8_), 10 m. The South Roosevelt Regional State Park comprises an area of approximately 90 square miles, lying along the Little Missouri just N. of US 10. In addition to the fantastic beauty of the Badlands buttes, it contains a petrified forest, and one of the largest burning coal mines in the Badlands.
