68. South Beach, Staten Island
The beaches along the south shore of Staten Island are not as popular
as the Atlantic beaches of New Jersey or Long Island (see Figure
159 on the Raritan Bay page). This is in part because of the traditionally
poor water quality of the bay, the abundance of garbage that washes ashore,
and the cost and effort it takes to get to Staten Island from the rest
of the City. In recent years, great effort has been taken to clean up
the Staten Island beaches and to improve the park facilities along the
south shore, particularly at Great Kills Park (part of Gateway National
Recreation Area). Still, a walk along South Beach provides a scenic view
of the Outer New York Bay (Figure 183).

In general, the beaches along the south shore are largely artificial
or modified. An examination of the sand near the Verrazano Narrow Bridge
shows the character of local sand sources. The sand fragments are much
more angular than on the Atlantic beaches, and it includes an abundance
of feldspar, mafic fragments and sedimentary iron, reflecting the sediment
source areas in the Highlands Region and the Newark Basin. Although the
beach has been partially replenished artificially, this sand is in part
derived from the progressive erosion of glacial till and moraine materials
exposed to erosion in the vicinity of the Narrows northwest of the Verrazano
Bridge.
