Went there for the first time this fall. I did not know this existed until a friend took us there. It is a natural lake that is 45 feet deep and clear enough to see the bottom. There is no swimming and the water temp is in the 30's all year - very cold. This is a small lake, but very beautiful. The walk from the parking area is less than 1/4 mile. It is also flat and a very easy trail.
