Are you talking about Reiter Ponds on the Skykomish? If you are referring to the big gravel pit that has no trespassing signs I think it is more of a liability issue for them. I have many times walked through the pit and there were workers all over, I have even talked to them. I do not think they care if you walk through, I think the no trespassing signs are up in case you get run over by a dump truck then you may have a hard time suing them.
