The Shrewsbury Rocks are a wide area of rocky bottom that stretches from fourteen feet of water out to the fifty-foot mark off of Monmouth Beach. Some of the formations are twenty feet tall or more and can be very pretty under good conditions, which are unfortunately seldom this far north. The stone itself is a type of sandstone known as Greensand.
This is a scattered wreck not far from the Great Isaac, clearly a small steel-hulled ship of some kind. There is a boiler and what looks like the remains of a section of hull sticking out of the sand a foot or two.
