The crystalline limestones in southeastern New York include 

 small areas in the Highlands gneiss complex which are perhaps the 

 equivalents of the Adirondack Grenville limestones. They are 

 found along Sprout Brook valley, north of Peekskill, as a narrow 

 belt 5 or 6 miles long; near Garrison and Cold Spring, Putnam 

 county; and in various parts of Orange county on the west side of 

 the Hudson river. They are magnesian, but do not usually carry 

 enough magnesia to be classed as dolomites. In some places they 

 are fairly free from silicate impurities. 



In southern Orange county a white crystalline limestone is devel- 

 oped on a considerable scale, mainly in the towns of Warwick, 

 Minisink and Goshen, as an extension of the New Jersey (Franklin 

 Furnace) limestone belts. It occupies the valley that borde s the 

 Precambrian gneiss ridges in the town of Warwick and may be seen 

 in outcrop near Warwick village and more especially about New 

 Milford, where it underlies a series of low hills and is in m^any places 

 thinly soiled. Although not quarried to any extent in New York 

 State there are very extensive operations just across the line in 

 New Jersey. Another belt of the limestone outcrops around Pine 

 Island^and probably underlies much of the low marshy tract known 

 as the Drowned Lands of the Walkill. Quarries have been opened 

 just southeast of Pine Island. The limestone is a mediimi to coarse
