Cape May Formation — Local Details. 197 



most of the tract covered by it between Cohansey Creek and 

 Maurice River has an elevation of less than 20 feet. 



Maurice River. — Up Maurice River it appears in a character- 

 istic way on both sides of the stream nearly to Franklinville, 

 and perhaps beyond, though it here becomes indistinguishable. 

 It covers a belt several miles wide up to Millville, and a nar- 

 rower belt farther north. It also covers a wide belt in the lower 

 parts of the valleys of Manumuskin and Manantico creeks, 

 extending up nearly to Bennetts Mill in the former valley, and 

 to Hange's Bridge in the latter. 



In the valley of Maurice River it attains an elevation of 90 

 to 100 feet in the vicinity of Porchtown and Malaga, 90 feet 

 at Union Grove on the tributary east of Rosenhayn, and about 

 60 feet in the valleys of Manantico and Munumuskin creeks. 



The material of the formation was derived from the Bridge- 

 ton, Pensauken, and Tertiary formations of the drainage basin. 

 It is sandy for the most part, and but little of the land covered 

 by it is cleared. There are few exposures, and detailed study 

 of it has not been made. Eolian sand affects its surface at some 

 points, as along the railway west of Vineland. 



East of Maurice River the formation expands widely, cov- 

 ering most of the area south of a line running from Manumus- 

 kin to Great Egg Harbor, though an area of a few square miles 

 east of Bricksboro rises above the level of the formation, which 

 seems to be limited approximately by the 40-foot contour. 



IN THE ATLANTIC DRAINAGE BASIN. 



Great Egg Harbor River. — The formation extends up the val- 

 ley of Great Egg Harbor River to Weymouth, several miles 

 above Mays Landing, in a broad belt on both sides of the stream. 

 In narrower and ill-defined belts, it is found still farther up the 

 valley, but it nowhere rises above 50 feet or so, in distinguish- 

 able development. Above Weymouth it is doubtless represented 

 under the marshy bottoms of the valleys. 



Betiveen Great Egg Harbor River and Toms River. — East of 

 Great Egg Harbor River, it is limited chiefly to elevations be- 

 low 35 feet. It expands in bay-like form in the lower part of
