Underwater pyramids of Walden Pond.
One of the strangest attributes of Walden Pond is existence of
underwater stone pyramids. The presence of stone pyramid by itself
should surprise nobody – farmers clear place for agriculture.
But at Walden Pond there is no and cannot be any arable land
as it seems. At least now when forest is near shore line. One
explanation is that water level years ago was about twenty feet below.
