Not illustrated. 1920 Excerpt: ... Bailey Willis in producing folds and faults by lateral pressure.1 This fault is in a 2o-foot terrace on the west side of Walnut Fig. 33.--Unsymmetrical fold with two thrust faults, the larger one in the upper sandstone bed and the smaller in the lower bed at the left edge of the picture, Paine Creek, 6 miles east of Painesville, Ohio. Fig. 34.--Two thrust faults with a small anticline between, the larger fault being at the left of the fold, along a southern tributary of Elk Creek, j mile south of Girard, Pa. Creek between the two railroads 10 miles southwest of Erie. The fault plane dips 30 south, and the throw is about 2 feet 6 inches. 1 Bailey Willis, Thirteenth Ann. Kept. U.S.G.S., Part 2 (1891-02), Plates 91, 93. Other ways in which faults are related to folds are shown in Figures 33 and 34. The illustration in Figure 33 shows a marked unsymmetrical fold and two faults. The fold is 47 feet wide, with a southwest dip of 8 and a northeast dip of 52. The axis is N.6oW. The upper n-inch sandy stratum has been faulted at the right of the fold, being thrust 4 feet 6 inches over the horizontal part of the same stratum at the right. At an interval of 3 feet 8 inches below this stratum is a second i6-inch sandstone bed, which because of the fold, is carried beneath the level of the creek at the right. This lower heavy stratum, which is sharply folded toward the right, is overthrust at the left edge of the picture, for a distance of 21 inches, where the fault plane dips 17 toward the northeast. The high part of the bank above the fold is about 40 feet. This fold and the faults are just east of the wagon bridge across Paine Creek, six miles east of Painesville, Ohio, and are in the Chagrin formation. Still another relation of faults to folds is shown in Figure 34, .
