Artists were the Delaware Water Gap’s most effective discoverers. Inadvertently, they publicized it. They almost literally put it on the map. Arrested by the symmetries of this geomorphological phenomenon, they sketched, painted, and engraved it. The earliest dated work is the Strickland Aquatint, i830, with a long and narrow flat-bottomed Durham boat in the foreground on the river, four crewmen standing at their oars, a steersman (also standing) in the stem, and in the background the wildwoods rising up the mountain with its deep, improbable incision. Cutting and filling, a stream would cross its own valley, gradationally leaving gravels under sands under silts under muds under fine grains that settled in overbank floods. With co-working space amsterdam nothing missing, the sequence was before us now, and was many times reiterated in the rock-a history of the migrations of the stream as it spread layer upon layer through its subsiding valley, 412, 411, 410 million years ago. In i832, Asher B. Durand came upon the scene. Durand was one of the founders of what in time would be labelled the Hudson River School. The term was a pejorative laid by a critic on painters who went outdoors to vent their romantic spirits. They went up the Hudson, they went up the Rockies, and they went into the Water Gap unafraid. Durand painted another Durham boat. His trees looked Japanese. The picture was published after Durand himself made a copper engraving. It contributed to the axiom that where an easel had stood a hotel would follow. Kittatinny House was established in i833, sleeping twenty-five. Anita chipped out a piece of Bloomsburg conglomerateevidence in itself that the stream which had made it was by no means spent. The rolling Silurian countryside must have been lovely-its river valleys velvet green. There were highland jaspers among the pebbles in the sand. The co-working space rotterdam early geologists began arriving in i836, led by Henry Darwin Rogers. They were conducting Pennsylvania’s first geological survey. In the deep marine Martinsburg slate and in the mountain strata that stood above it-in the “plication” and the “corrugation” of the sediments-Rogers saw “stupendous crust-movement and revolution,” the “most momentous” of ancient times, and reported to Harrisburg what would eventually become known as the Taconic and Alleghenian orogenies. He decided that something had wrenched the mountain in New Jersey several hundred feet out of line with its counterpart in Pennsylvania.
