  Title: Bear Island (Lake Winnipesaukee)
  Passage: Bear Island is the second largest of the 262 islands in Lake Winnipesaukee in New Hampshire, United States.  In the summer it is accessible only by boat because it is not connected to the mainland via a bridge.  In the winter it can be reached by crossing the frozen lake, including by snowmobile.  According to the Lake Winnipesaukee Historical Society, the island got its name when a few hunters along with a few members of the Pennacook tribe were sent to survey the island.  However, they encountered a few bears, which they decided to hunt.  Originally the island was named "Big Bear Island", which was later shortened to "Bear Island" when the island was annexed by the town of Meredith in 1799.
