No i didnt . This was completely spontaneous , i never usually seen stuff like this in the water , but like i said there was a storm for that could be the reason why im finding shards and things . I honestly dont think the park would care - Your not from here so you wouldnt know . The north woods of Central park is a ghetto area that has been neglected . most of the official archaeological sites from Seneca Village or war forts (from the war of 1812) Are not near the stream where i found this. So i think its a free for all , i seen folks with metal detectors out here before too . Never had any problems with park crew , i think the only people they would care about are tweakers and those disturbing visitors , or causing trouble , not someone picking up stones or shards from the park .
