She had scarce uttered the words when the road jumped to the right and through a nameless gap and past a roadcut twenty metres high-Bald Eagle quartzite-and then more and higher roadcuts of Juniata sandstone in red laminations dipping steeply to the west. “I take it back. This is one hell of a series, let me tell you,” Anita mid. More rock followed, rock in the median, rock right and left, and we ran on to scout it, to take it in whole. The road was descending now through gorges of red rock-the results of precision blasting, of instant geomorphology. Their depth increased. They  co-working space amsterdam shadowed the road. And in their final bend was the revealed interior of a mountain, geographically known as Big Mountain. There had been a natural gap, but it had not been large enough, and dynamite had contributed three hundred thousand years of erosion. The entire mountain had been cut through-not just a toe or a spur. “Holy Toledo! Look at that son of a bitch!” Anita cried out. “It’s a hell of an exposure, a hell of a cut.” More than two hundred and fifty feet high and as red as wine, it proved to be the largest man-made exposure of hard rock on Interstate So between New York and San Francisco. It was an accomplishment that might impress the Chinese Geological Survey. “When you’re doing geology, look for the unexpected,” Anita instructed me, forgetting the Zagros Mountains. We stopped on the shoulder in the shadow of the rock. “Holy Toledo, look at that son of a bitch,” Anita repeated, with her head thrown back. “Mamma mia!” The bedding was aslant in long upsweeping lines, of which a few co-working space rotterdam were green. Almost due south of Lock Haven and thirty-one miles west of the Susquehanna River, it was Juniata sandstone, brought down off the Taconic uplift and spread to the west by the same system of rivers that transported the rock of the Delaware Water Gap.
