Eastern Border Fault
About 200 million years after this collision and the formation of Pangea, during the middle of the Mesozoic Era, the Atlantic Ocean floor started spreading and great extensional forces were experienced, resulting in faulting. Connecticut’s famous Eastern Border Fault was created, 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, creating 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.

Famous quotes containing the words eastern, border and/or fault:
“From this elevation, just on the skirts of the clouds, we could overlook the country, west and south, for a hundred miles. There it was, the State of Maine, which we had seen on the map, but not much like that,—immeasurable forest for the sun to shine on, the eastern stuff we hear of in Massachusetts. No clearing, no house. It did not look as if a solitary traveler had cut so much as a walking-stick there.”
—Henry David Thoreau (1817–1862)
“I have, indeed, even omitted facts, which, on account of their singularity, must in the eyes of some have appeared to border on the marvelous. But in the forests of South America such extraordinary realities are to be found, that there is assuredly no need to have recourse to fiction or the least exaggeration.”
—J.G. (John Gabriel)
“A man will teach his wife what is needed to arouse his desires. And there is no reason for a woman to know any more than what her husband is prepared to teach her. If she gets married knowing far too much about what she wants and doesn’t want then she will be ready to find fault with her husband.”
—Barbara Cartland (b. 1901)
