- Lake Winnipesaukee and her islands provide us with much interesting history. The islands were used by Native American Indians for perhaps five thousand years.
- The Indians in this area were called the Pennacooks. Many of our words come from the Indians. For instance, Winnipesaukee means “beautiful water in high place”.
- Don’t be surprised if you find an arrowhead or artifact on the shore of your island. An Indian probably stood in this very spot.
- Later in history, there were hotels on both Diamond and Bear Islands. On Cow Island, a gentleman by the name of Pillsbury operated a grist mill and supplied flour to local people.
- One expression about Lake Winnipesaukee is that there is an island for every day of the year. Realistically, there are about 270 big enough to be called islands.
- Birch bark canoes were decorated with the makers distinct markings.
- Many centers of the islands are owned by the individual island associations and are restricted from being built upon. Usually, the centers are saved for exploring, hiking, and nature walks.
- The shorelines are primarily rocky with wild blueberry bushes galore and scattered natural beaches. The interiors are generally treed with hardwood and evergreens, on which deer graze.
- Stonedam, Ragged, Five Mile, and Blanchard Islands (among other smaller islands) are owned by the Lakes Region Conservation Trust and are available for nature walks and hikes.
- There are also two sanctuaries for loons, the Melvin Island and the Ragged Island Loon Sanctuary.
- “The Forties” – Round, Pop, Fish, LeRoy, Crescent, Saints Rest, Kinneho and Breezy Islands are part of a group of islands between Mark Island and Welch Island referred to as “The Forties”.
