Lucky too, the rock quarry is really and old rock qaurry. It is the deepest part of the lake, 110'. It is very tight in there. The boats in the background are lucky it did not spread. The entrance to the qaurry is big enough for three boats side by side to safley pass thru without grounding, maybee 4 shore to shore, The actual qaurry is only about 1 football field wide by 4 long. On busy days, it gest so packed it is hard to get out of.
