It looks like a great fault (a rift, even). Imagine something like that happening across the Mississippi River, the Columbia or the Hudson River?
What could be similar in the contiguous United States? How about The Fall Line that caused one of the first hydro-power industrial sites in the original 13 colonies. Alexander Hamilton (see AHA@Twitter.com), had a part in the development of the site.
The Fall line extends into Pennsylvania, near Philadelphia. Does anybody want to put together a collection of 200 New Jersey water wells and about 100 Pennsylvania wells and draw a structure map along the Fault?
