"A series of great dislocations with upthrows on the east side
traverse eastern North America from Canada to Alabama. One of these
great faults has been traced from near the mouth of the St. Lawrence
River, keeping mostly under the water up to Quebec just north of the
fortress, thence by a gently curving line to Lake Champlain or through
western Vermont across Washington County, N. Y., to near Albany. It
crosses the river near Rhinebeck 15 miles north of Poughkeepsie and
continues on southward into New Jersey and runs into another series of
faults probably of a later date, which extends as far as Alabama. It
brings up the rocks of the so called Quebec group on the east side of
the fracture to the level of the Hudson River and Trenton.
"Catskill Mountains. For many miles on this railroad are beautiful
views of the Catskill Mountains, 3,800 feet high, several miles
distant on the opposite or west side of the river, and which furnish
the name for the Catskill formation. The wide valley between them
and the river is composed of Chemung, Hamilton, Lower Helderberg and
Hudson River.
