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)
