The 1872 expedition was halted at the shore of a dark and silent underground lake filled with water “sweet to the taste.” The size of the body of water could not be determined since vision was limited to the span of torchlight and “stones thrown by the strongest arm failed to reach the opposite side….” Plans to launch a rubber boat on the subterranean lake surface apparently never went fulfilled. Presumably the untouched waters still await the arrival of a modern Columbus.
