In the United States, the '''Manhattan Prong''' of the [[New England Uplands]] is a smaller belt of ancient rock in southern [[New York (state)|New York]] (including [[Manhattan]], [[the Bronx]], and segments of [[Brooklyn]] and [[Staten Island]]), parts of [[Westchester County, New York|Westchester County]], and upland portions of southwestern [[Connecticut]]. The [[bedrock]] underlying much of Manhattan consists of three rock formations: ''Inwood [[marble]]'', ''Fordham [[gneiss]]'', ''Manhattan [[schist]]'', and ''[[Tuckahoe marble]] (Inwood marble)'', which are well suited for the foundations of Manhattan's [[skyscrapers]].<ref>{{cite book|title=Rise of the New York Skyscraper, 1865&ndash;1913|page=24|author1=Sarah Bradford Landau|author2= Carl W.

The Manhattan Prong and the [[Reading Prong]] are separated by the [[Newark Basin]] in the south, but the two features merge at the northern terminus of the Newark Basin in the vicinity of [[Peekskill, New York|Peekskill]], [[New York (state)|New York]]. A band of mountains that rise nearly one thousand feet along the northwestern margin of the Newark Basin in New York and New Jersey are called the [[Ramapo Mountains]]. Another belt of ancient metamorphic and [[igneous rock]] crops out along the southern margin of the Newark Basin south and west of [[Trenton, New Jersey|Trenton]], [[New Jersey]]. In this region, the rocks are referred to as part of the [[Trenton Prong]].
