three miles from J. D. Honaker's store. Thence to New river the road is 

 in the limestone between the two faults. The creek approaches the Buck- 

 horn fault very closely near the line of Giles county, but the Wenonah 

 fault, whose course is marked by the Valley ridge, is touched nowhere by 

 Wolf creek below the gap near Honaker's. The dips in limestones be- 

 tween the two faults vary greatly, being from fifteen to forty degrees 

 along the creek ; but the rate diminishes toward New river, where it 

 rarely exceeds twenty degrees. Though underlaid by limestones and cal- 

 careous sandstones, much of this Wolf Creek valley is very poor. Great 

 fragments of Medina are numerous and the disintegrated sandstone has 

 contributed most largely toward formation of the detrital covering. 



The valley between Buckhorn and East River mountains is reported to 

 be "freestone." No examination of its structure was made, but there 

 appears to be a synclinal here, in which case the surface rocks would be 

 Silurian shales. 



The valley is contracted near the mouth of Wolf creek and the locality 

 is known as the "Narrows." The crest of Wolf Ci'eek mountain is 

 carried northward in a bold knob which overlaps the Valley ridge. Thence 

 it recedes southward, limiting the broad deep valley of Mill creek, to 

 return northward and fdrm the bold knob of Pearis mountain. The point 

 of this mountain is at about two miles from Pearisburg and there the 

 Medina outcrop curves southward under the influence of the Kimberling 

 anticlinal. The Valley ridge becomes indistinct where the fault is crossed 

 by the pike near Wenonah station. Thence to Pearisburg the road lies in 

 Calciferous and Trenton limestones. The S5rnclinal north from the Kim- 

 berling anticlinal is crossed by the Dublin pike at the southerly end of 

 Pearisburg and in this is the "Angel's Rest" or terminal peak of Pearis 

 mountain. The outcrop of Medina climbs the anticlinal as the fold de- 

 clines, crosses it at the head of Sugar run and then moves eastward along 

 the southerly side of the anticlinal. It soon recedes toward the west as it 

 ascends the weakening anticlinal of Sinking creek and finally disappears 

 against the Saltville fault.* That fault is crossed by the Dublin and 

 Pearisburg pike at a very little way north from Poplar hill, where the 

 Trenton and Calciferous are in contact and the road passes into the Rich 

 valley between Big Walker's mountain and the Saltville fault. 



A road, leaving the pike north from Poplar hill and leading to New 

 river at Scott's ferry, crosses the Saltville fault at four miles from the pike 

 or at a little more than one mile by Walker's creek above Stafford sville. 

 Erosion here, as on the pike, has cut away all rocks higher than Trenton 

 limestone from the north side of the fault, but, within a short distance, the 

 Medina appears again and forms Buckeye ridge, the northern boundary of 

 Rich valley to and beyond New river. The dying away of the Walker's 

 Creek anticlinal permits the Walker's Mountain outcrop of Medina to 

 advance northward so that the valley is narrow near New river.
