EXPOSURES BETWEEN TIVERTON FOUR CORNERS AND THE NORTHEAST SIDE 



OF NANNAQUACKET POND. 



Northwest of Tiverton Four Corners a tract of meadow land and marsh 

 runs toward the bay North of this, a httle east of north from the hist 

 exposure described, the coarse conglomerate is exposed in several places. 

 The more northern exposure shows a strike of N. 32° E., dip 50° W, 

 Eastward, on the western side of the hill, west of the road, are several 

 exposures of coarse conglomerate not showing a marked strike or dip. 

 The line of strike of the exposure described above, if extended, would reach 

 a hill showing steep cliffs on the western face, where interbedded sandstones 

 show successively, northward: strike N. 50° W., dip 60° W.; strike N. 76° 

 W., dip nearly vertical, and strike N. 30° W., dip 70° W, Northward a 

 small exposure shows a strike N. 5° E., dip about 70° W. A large steep expo- 

 sure northward has the same northerly strike. The next has a strike N. 45° 

 W., dip 60° W. Northeastward, nearer the road, are several exposures, the 

 most westei-n of which has a strike north-south, dip steep west. Then, 

 after a rather long interval, in the southeast angle of tlie crossing of the 

 Tiverton with the Sapowet Point road, the coarse conglomerate is exposed 

 again with a strike of N. 70° W., dip 35° SW. The most westerly exposure 

 nox-th of the Sapowet Point road shows a strike also N. 05° W., dip 60° W. 

 Nearer the crossroads the dip seems very low southw^est. At an inter- 

 mediate point northward the strike is N. 15° W., dip 30° W. No satis- 

 factory bedding is shown by the exposures in the little creek which runs 

 west about a quarter of a mile from the crossroads. In the valley of this 

 brook, however, a Httle east of the line of outcrop of the conglomerate, occurs 

 a sandstone and shale exposure, in places of a rather dark color, which 

 may represent the sandstone series underlying the coarse conglomerate. 

 Unfortunately, the exposure is not large enough to determine the matter. 



North of this little stream, on the western side of the summit of the 

 hill, a series -of exposures continues northward. One of these shows a 

 strike N. 40° E., dip steep, perhaps 60° W. (uncertain). The most northern 

 exposure, on the north side of a circular embankment, shows strike N. 80° 

 E., dip 85° N. Northeast of the private road, on the slope toward Nanna- 

 quacket Pond, an exposure has a strike N. 85° E., dip 75° N. After that 

 the exposures continue to trend northward east of Nannaq^uacket Pond. 

 Coarse conglomerate is exposed along the Tiverton road not far north of
