European settlers were also attracted to Grey Rocks (named for nearby granite outcroppings) for fishing, agriculture and recreation. The NH Fish & Game Department gill netted landlocked salmon for stocking of the State fish hatcheries into the 1950’s, and a State record lake trout (28.5 lbs) was caught in Newfound on April 24, 1958. From 1941 to 2009 the Grey Rocks land was operated as a marina.

In 1927 Dorothy Ellingwood McLane (1885-1982), fondly known as “Granny Mac,” began purchasing the land and buildings that became Grey Rocks Camp. From the mid-1920’s to the late 1930’s she operated the Grey Rocks Camp for girls on this land and along the shore near the Hebron Town Beach.

In December 2011, the Grey Rocks Conservation Area was donated by Andy & Linda McLane in honor of Dorothy McLane, Andy’s grandmother, to preserve its unique habitat and diverse wildlife population and for the enjoyment of all future generations.
