There is both a rock ledge and new marker there, which I mentioned
in May.
As
camp guy has implied, the marker kind of "sticks out into" the normal traffic pattern there, so it will likely become a headache for the people who do Winnipesaukee's marker maintenance.
(The marker does not appear on Bizer's, BTW).
Wolfeboro Matt: I found two smaller "logs" similar to what you are describing. If yours was cut off by chainsaw -- and has no bark -- it may have been one of those dock piling remnants (especially if it was slippery, suggesting no bark).
I think it's the construction-barge people cutting off the tops* and sharpening the tips** of dock pilings.
*...after driving them in, to "level" a new dock piling
**...the bottoms of pilings to a point -- to drive them in faster.
Somebody needs a talking-to about where to discard "the excess".
