PARADISE ROOKS. 297 



mined, notwithstanding evidence of some degree of folding. A subsidiary 

 ridge west of the main line of outcrop shows almost vertical dips — 80° E. 

 on the east side, 80° W. on the west side — owing to a moderate diver- 

 gence of the bedding planes of the two extreme layers. Southeastward 

 the main line of outcrop begins again, with a dip of 85° W., and this 

 nearly vertical dip is maintained for some distance south, becoming 70° 

 W. at the most southern exposure, between the middle and western streams 

 entering the reservoir. 



A very important point should here be noted. While the inass of con- 

 glomerates forming the western and higher eastward-dipping Paradise 

 Ridge is of considerable thickness, that forming the lower and practically 

 vertical-dipping eastern ridge is only one-third or one-fourth as thick. 

 So that, although a synclinal structure might be imagined between these 

 two ridges, there is not as much conglomerate exposed on the east side 

 of the supposed syncline as would be expected in the case of such a 

 structure. Another equally important point is this: A continuation of the 

 line of strike of the more eastern Paradise Ridge would reach a solitary 

 coarse conglomerate exposure at the west end of Sachuest Beach, with 

 strike N. 14° E., which has a dip of 40° E., but in order to agree with 

 the synclinal structure demanded northward its dip ought to be west. Less 

 important, because the exposures are not equally satisfactory, is the vertical 

 dip shown by the exposure east of the north end of the continuous eastward- 

 dipping line of exposures already described, where the dip is 50° E. The 

 dip of the more eastern exposure should be westward to agree with synclinal 

 structure in this region. The second, more eastern, ridge shows in places 

 evidences of local folding. 



In view of all the facts observed it seems reasonable to suppose that the 

 Paradise ridges form a great eastward-dipping series of conglomerates on 

 the western side of a syncline. The eastern of the two ridges dips east- 

 ward only at the southern^ end. North of the reservoir the conglomerate 

 beds of this eastern ridge are aifected by a local flexure traversing the 

 series a little diagonally, which has bent these beds downward and moder- 

 ately overturned them northward, so that the almost vertical but somewhat 

 westward dip of the eastern ridge along its southern end is changed to an 

 almost vertical but slightly eastward dip near its northern end, the dip of 

 50° E. in the field a considerable distance north of the second x'idge, and
