Figures 4-26a and 4-26b illustrate the morphology of this spit in 1891, when
Mattituck Inlet was in a natural state, to 1955. The spit experienced rapid growth
due to the landward breach in the 1930s. After the landward extension of the east
jetty in 1946, this spit began to migrate south and east under wave attack and to
transport by the flood current. Panel d of Figure 4-26b shows the spit in 1955,
when it had begun migrating. The migration of this spit and its evolution into the
present-day flood shoal are analyzed next.
