Then follow main street. you will see a sign that says red granite correctional institute and a set of stop lights. keep going straight and the quarry will be on your right. its by the post office then you take a left. This place is alot of fun. the cliffs range from about 10ft to 25ft. there is a tree you can jump out of that is about 35-40 ft. There usually is quite a bit of people there on a nice sunny day. the water is usually fairly warm. I hear the water is about 100-300 feet deep. you dont need to worry about hitting any rocks or anything.
