2010 Map of Pattersquash Island

About this map

Pattersquash Island sits at the center of this coastal survey, where the protected waters of Narrow Bay meet the thin barrier of Great South Beach. This maritime landscape is defined by the tidal fingers of Unchachogue Creek, Johns Neck Creek, and Sheepen Creek as they drain into the bay from the mainland. On the northern shore, the residential patterns of Shirley and Mastic Beach are visible, showing the modern layout of these Long Island communities. To the west, Smith Point and the adjacent Johns Neck anchor the peninsula, while the vast expanse of the Atlantic Ocean dominates the southern half of the sheet. The map provides a precise look at the 2010 shoreline and the intricate relationship between these coastal settlements and the shifting sands of the outer barrier beach.
