The Merrimack, which flows southerly from Franklin, New Hampshire to Lowell, makes a northeasterly turn there before emptying into the Atlantic Ocean at Newburyport, Massachusetts, approximately downriver from Lowell. It is believed that in prior ages, the Merrimack continued south from Lowell to empty into the ocean somewhere near Boston. The glacial deposits that redirected the flow of the river left the drumlins that dot the city, most notably, Fort Hill in the Belvidere neighborhood. Other large hills in Lowell include Lynde Hill, also in Belvidere, and Christian Hill, in the easternmost part of Centralville at the Dracut town line.
