Maritime Geocaching Association
Please note: The island is almost completely private property. Please respect that on your visit. Do not cut across lawns or people's house lots or fields on your visit; stay on the roads, follow the shoreline and beaches, and usually there are old hunting paths just inside the edge of the woods when the shoreline turns into cliffs that meet the forest edge. These caches are present on the condition of respect from visiting cachers. Thankyou. 
The Big Pond is the largest body of "fresh" water on the island. The sand bar seperating it from the ocean however is sometimes breached in large storms, so the water is actually part salt water. This pond was a swimming spot in the past since it was the only pond large enough for it (and warmer than the ocean) though the drop-off in a bit from the sand bar meant your feet could lose solid ground quickly if you weren't careful. In the winter it was the largest spot for skating.
The pond is located on the west side of the island next to the Land Hill, where nets used to be stretched out to dry in the seine fishing days. A good view of the island can be aforded from the top of the hill.
Tales are told on the island of Captain Kidd's treasure being buried in the Big Pond. If I recall, when my brother was young and the pond was extremely low one summer, he thought he could see something like a chest in the mud on the bottom out in the pond. I believe he also found something like part of an old wooden chest once back at the pond. Coincidence? Something washed over the sand bar in a storm? You decide.
The only treasure you can count on finding now is the cache. And, though it isn't gold, there is a copper Lunenburg County Cachers geocoin in the cache for the First to Find.
Terrain is at 5 since you need a boat to reach the island. Once there, the terrain is about a 2.5 for this cache.
The cache is situated on land protected by the Nature Conservancy of Canada, off the end of the Aspotogan Peninsula. This area contains delicate coastal forest, barren, and pond ecosystems, providing habitat for many waterfowl and migratory bird species. The Nature Conservancy of Canada is a national non-profit land conservation organization and they encourage you to enjoy the Natural Area, but be respectful of its protected status by staying near the roads and trails, and respecting all signage.
