Abstract The Meers fault scarp trends ESE-WNW along the northern edge of the Meers Valley in Commanche County, southwestern Oklahoma (Fig. 1 ). The impressively straight scarp can be traced for 16 mi (26 km). The southeastern two-thirds of the scarp intends across land that is under relatively intensive agricultural use, and the northwestern third extends across hilly open range. This land usage reflects the underlying Permian bedrock shales to the southeast and conglomerates to the northwest. The most visually impressive and instructive lengths of scarp are developed in the conglomerate terrain. Access procedure to a convenient length of the scarp in this terrain is as follows. First, contact Mr. Charlie Bob Oliver, manager of the Kimbell Ranch. The ranch house is located in Blue Creek Canyon on Oklahoma 58. Mr. Oliver has been closely involved in recent work on the fault and, if notified in advance, can make a key to the ranch tracks available. Oklahoma 58 must be followed south of Stumbling Bear Pass to a county road (Fig. 2). This road should then be taken for just over 1 mi ( 1.6 km) west to a group of houses north of the road. At this point a decision must be made with respect to the condition of a ranch track which trends north by the houses. This road is impassable for most vehicles after a rain (the alternative is a walk of about 1.5 mi; 2.4 km). The track is followed north for about 0.5 mi (0.8 km)

Abstract The Bally Mountain Range is located in eastern Kiowa County in southwestern Oklahoma (T.6N., R.14W.). The closest important road is Oklahoma 58 (Fig. 1). This road can be accessed from the H. E. Bailey Turnpike by taking the Medicine Park exit a few miles north of Lawton. Alternatively, the route can be joined from the north by taking the Hydro exit from 1-40. The easiest way of reaching the site is to proceed north on Oklahoma 58 for 3 mi (4.8 km) from its junction with Oklahoma 19, then turn west along a partly paved county road for 3 mi (4.8 km). Just before reaching the most prominent hill in view (which is Bally Mountain), turn right on an unpaved road and proceed north for a few hundred yards to the only inhabited house (on the west side of the road). This is the home of Mr. W. Hodges, the principal landowner in the area, where permission to visit the site should be sought. In common with several other landowners in the area, Mr. Hodges freely allows large parties of students access to his land on condition that they do not smoke or leave litter and that they close all gates, etc. His house is very conveniently situated; immediately to the west is the bulk of Bally Mountain, which is composed of Carlton Rhyolite. This hill is 1,900 ft (580 m) high and rises 350 ft (107 m) above the surrounding plains. To the north and east rises the remainder

Abstract Zodletone Mountain, a 250-ft-high (76 m) eminence in Kiowa County, southern Oklahoma, constitutes the northernmost member of the Slick Hills Range and rises 1,649 ft (500 m) above sea level (SW¼SW¼ Sec.9, T.6N., R.14W. Saddle Mountain 15-minute Quadrangle, Oklahoma). The best approach to the mountain is by following Oklahoma 58 south from Carnegie for 7 mi (11 km). At this point turn west along an unpaved section road for 3 mi (4.8 km), then south for 0.5 mi (800 m) to a white two-storied farmhouse, which is the home of Mr. Don Trobe (Fig. 1). Obtain permission to visit here. (Mr. Trobe, like everyone else hereabouts, has been very supportive of geologists. However, no smoking and no litter, please.) About 0.5 mi (0.8 km) south of Mr. Trobe—s home, turn west along another section road and drive 1.7 mi (2.7 km) to a silver gate at SE¼SW¼Sec.16, T.6N., R.14W. From here a fair-weather track runs north to the northeast side of Zodletone Mountain. Follow this track to its termination, park, and walk (but beware of rattlesnakes).

Abstract The Wichita Mountains extend for about 65 mi (105 km) northwest from Lawton, Oklahoma (Fig. 1). Four sites are described here: 27—Quartz Mountain State Park in the western part of the Wichita Mountains, near Oklahoma 44A; 28—The Tom Steed Reservoir area, along U.S. 183 in the central Wichita Mountains; 29—French Lake, south of Oklahoma 49; and 30—the Mt. Scott area, north of Oklahoma 49 in the eastern Wichita Mountains. Specific directions to each site are given with the site descriptions.

Abstract Blue Creek Canyon is located approximately 15 mi (24 km) north-northwest of Lawton in southwestern Oklahoma (T.4N., R.13W.). Oklahoma 58 (Fig. 1) runs through the canyon. The area can be most easily reached from Lawton by taking the Medicine Park exit from the H. E. Bailey Turnpike a few miles north of Lawton. The entire area described here is part of the Kimbell Ranch, owned by Mr. and Mrs. David Kimbell of Wichita Falls. The ranch house is situated at the south end of the canyon (Fig. 2) and is managed by Charlie Bob and Dixie Oliver. Both the Olivers and the Kimbells have greatly encouraged the visits of geologists, and several local universities use the area as a student training ground. Permission to visit should be sought from Mr. Oliver, and the usual common sense and courtesy extended. The ranch address is Star Route A, Box 124, Lawton, OK 73501. The Olivers carry their interest in geology to a remarkable level; during monitoring of the recently active Meers Fault, they had a seismograph installed in their bedroom as part of a regional network. The descriptions in this field guide are for a series of walks that start approximately 0.5 mi (0.8 km) north of the ranch house at Red Hill (a small hill of Carlton Rhyolite capped by Post Oak Conglomerate which is immediately west of the road) (Fig. 2). The walks are all rough and fairly hilly; exposure is more or less continuous. The area is well drained
