The upper contorted zone, whose base lies 65 or 70 feet below the top of the Trenton, is from about 5 to 12 or 15 feet thick. It is well exhibited along the path opposite High fall from which point it may be traced along the sides of the gorge for nearly 2 miles to The impure limestone layers of both the folded and nonfolded portions average only a few inches in thickness and are separated by thin bands of shale. Within the folded zone horizons the layers are, in some cases, scarcely folded or broken; sometimes they are gently folded or tilted; while most commonly they are highly folded and fractured (figure 1).. retft Fig. 1. The tipper contorted and broken zone as seen along the footpath opposite the crest of High fall at Trenton Falls. Drawn from nature. Numerous observations show the strikes of the contorted zone folds to be from N. 500 E. to N. 65° E. or practically parallel to the strike of the distinct folds in the Trenton formation in this region, as well as parallel to the strike of the well-defined fault-fold line passing through the village of Prospect (see geologic map). It should also be noted that these contorted strata occur only in a very local district.
