they , with ed 's permission , dug out the entrance way so that there was easy access to the cave.-they found several large chambers and passageways that led in different directions.-one tunnel had apparently been dug by hand and seemed to lead toward the wroes house ; but about half the distance from the cave to the house the subterranean passageway had collapsed and they could travel it no further without careful excavation.-they even mapped some of the chambers of the cave and several other people came to see it , too.-however , since it was on the wroe property and the wroes would be liable if anyone were to be injured in the cave , ed , on the advice of his attorney , felt it necessary to suspend any more visitation or exploration of the cave system.-they did discover that there had been a flat rock that covered an opening that dropped into the cave and the bank robbers had just removed that lid and dumped the gold , their disguises , and their dead partner into the cave through that hole.-through the years , the roots of the two old oak trees had wound around that lid and sealed it shut.-but , at any rate , andy and candy knew they would never forget their friend , shadowhawk .
