Appalachian Mountains
During the early
metamorphic rocks once very deep in the Earth's mantle
and uplifted during this time period.
Eastern Border Fault
About 200 million years after this collision and the formation of Pangea, during the middle of the Mesozoic Era, the
faulting. Connecticut's Eastern border fault was formed, a fault which begins in New Haven and stretches 130 miles up to Keene, New Hampshire. As a result, the land west of this fault was downset, resulting in a rift valley
and causing the land to tilt an average of 15 to 25 degrees. The fault is currently inactive. The formation of this basin eventually refilled with soft fluvial and alluvial sediments.
Ice Age
During
glacial meltwater
and clay in the wintertime as the lake froze until it was later drained.
