across so that there is a smooth surface. A similar conglomerate has 

 been found at a number of localities in the vicinity of Oakland and 

 Mountain Lake Park as well as to the south of these towns. 



To the northeast of the two localities Just described, on the hill crossed 

 by the Mountain Lake Park and Altamont Eoad, which forms the divide 

 between the branch and Ness Lick Run, are large loose blocks of conglom- 

 erate. This locality is on the western side of the axis but, on account of 

 a roll in the rocks, the shales on this ridge, by the side of the road, 

 show a dip to the south of east. 



Again on the first road turning to the northwest toward Hoop Pole 

 Eidge there are blocks of conglomerate on the ridge directly west of the 

 crossing over Ness Lick Eun which are not large but are, apparently, near 

 the horizon of a conglomerate stratum. Above is a brownish-red, thin 

 bedded sandstone. 



The base of nearly continuous reds occurs on this road 2800 feet to the 

 northwest and outcrops of thin bedded sandstone which are 340 feet below 

 the base of these reds give an average dip of 55° N., 40° W. If the 

 dip remained the same for the entire horizontal distance it would make 

 this conglomerate 2300 feet below the heavy reds at the base of the 

 Catskill foTmation while even a dip of 45° would give a thickness of 

 1960 feet. It is probable, however, that there are rolls in the rocks or that 

 the dip is less for part of the distance so that this estimate of the thickness 

 is considerably too great. But, 45 feet below the base of the heavy reds 

 on this road is a second conglomerate which is shown in the ditch at the 

 side of the road and there are fairly large blocks of it in the field. The 

 stratum measures from 5 to 7 inches in thickness and it occurs in the 

 midst of yellowish-green shales. There are numerous quartz pebbles in 

 the matrix which are not so lenticular in shape as those in the lower 

 conglomerate and the weathered blocks of the rock are stained a rusty 

 brown color. The average dip of the shales just above this conglomerate is 

 59° N., 50° W. and the strike is N. 40° E. 



The Oakland- Altamont Eoad crosses a ridge about 1 mile northeast 

 of the road leading to Hoop Pole Eidge, above described, which is the 

 third ridge west of the Mitchell liouse. The top of this ridge is covered
