Lakes and Cascades. Peterkill which flows along the west-sloping grits for half a mile, and then in high falls over the grit into the kill. East of the confluence there is a narrow depression known as Dark hole, which extends southeastward up the slope of the moun tain. It is rimmed by moderately high cliffs of west-dipping grit and was cut by a stream which empties into the Peterkill. On the southern side of Dark hole is the high plateau of which the eastern front constitutes the cliffs at the southeastern end of lake Awosting. The Peterkill valley from beginning to end extends along the western flank of the anticlinal on which lake Minnewaska is situated, and has a cliff of west-dipping grit on its western side and slopes of grit on its eastern side. Four miles below lake Awosting the kill passes over Awosting falls and then over a series of cascades, aggregating in all a fall of over 240 feet approximately. In Awosting falls there is a clear fall of sixty odd feet. They are a mile north of lake Minnewaska. In the gorge below the several falls there are high cliffs of grit for some distance, but owing to considerable pitch northward or down stream and a thickness of grit somewhat over 200 feet, the kill has not cut through to the Hudson shales. South of lake Awosting there are two small, shallow ponds on the summit of the mountain. Mud pond, at the head of Fly brook, the principal fork of the Peterkill, is one, and lake Mara tanza is the other. Lake Maratanza empties eastward by a branch of the Wallkill which pitches over the edge of the grit on the crest of the mountain, in a great fall into a deep gulf of Hudson shales. The locality is known as Verkeerder falls. Between Gertrude nose and Sams point the crest of the moun tain is very high, but for some distance the edge of the grit is broken into great terraces and there is a sloping bench of Hud son shales of some width at the base. Several branches of Wall kill drainage head in the crest of the mountain in this region and pass over the edge of the grit in falls of which the above mentioned Verkeerder falls are the most noteworthy. In this region the mountain narrows and some of the flexures pass out to the southward. This narrowing is due to recession of the edge of the sheet of the Shawangunk grit, which is closely related to the upward pitch of the flexures. This pitch increases the height of the mountain southward, but with increased height 5-NAT. GEoa. MAG., VOL.VI, 1894.
