Hi Bizer and All:
It has taken me three months to find it but I did! I'm not sure that I believe this, but, this is quoted from Bruce Heald's 1998 book entitled "The Lakes Region of New Hampshire - Volume II" (page 47) "Alton is situated in the bed of a river that was once the outlet of Lake Winnipesaukee to the sea. Geologists have demonstrated that the Merrymeeting River once flowed in the opposite direction of what it currently does."
