Location:Off US Route 3 in Laconia, at the south end of Weirs Beach.
Special Features:This is the site of a large boulder that was inscribed in 1652 with the name John Endicott, Governor of Massachusetts Bay, and the initials of two Massachusetts Bay Colony commissioners and two surveyors. The rock marked the assumed headwaters of the Merrimack River -- under the original Bay Charter of 1629, the northern boundary of the colony was fixed as a line three miles north of the Merrimack.
