prossee.] ULSTER AND DELAWARE R. R. SECTION. 61 
No. 1488 CI— SHOKAN. 
Exposure in brook, just below the post-office in Shokan village, of 
bluish-gray sandstone, with reddish shales a little farther up the brook. 
Ripple marks are common on the surface of the sandstones, and in 
addition are rather odd markings vertical to the bedding. The rail- 
road station at West Shokan, across Esopus Greek, is 533 feet, and the 
altitude of this exposure is not much less than the railroad level. 
No. 1488 1)1. — A ledge near the south margin of Little Mountain, 2 
miles from West Shokan, and well toward its summit. The ledge is a 
coarse-grained massive sandstone, about 790 feet above railroad level 
at West Shokan, which makes its elevation approximately 1,323 feet 
A. T. The summit of Little Mountain by barometer is 825 feet above 
railroad level at West Shokan, or, approximately, 1,358 feet A. T. 
Burgher's quarry, No. 1488 D2, on the southern side of Little Moun- 
tain, is about 715 feet above railroad level at West Shokan, or, approxi- 
mately, 1,248 feet A. T. The rock is a bluish-gray coarse-grained sand- 
stone, which is rather massive, although some flags have been taken 
out. There is a shaly layer which in places is a blue argillaceous shale, 
containing plant stems, while fragments of fossil plants occur occasion- 
ally in the massive sandstone. 
No. 1488 Al. — Quarry 2h miles up the Ulster and Delaware Railroad 
from West Shokan and 1 mile up the mountain to the west. Bluish- 
gray rather coarse-grained sandstone, with shaly layers which contain 
abundant poorly preserved plant stems. The quarry is 565 feet above 
the railroad track at the switch. 
No. 1489 Bl.— BOICEVILLE. 
The Avery quarry is three-fourths of a mile north of Boiceville and 
one-fourth mile up the hill west of the railroad. It is a massive, bluish- 
gray sandstone with arenaceous shales, in which are numerous poorly 
preserved plant stems. One fairly well preserved fragment of Lepido- 
dendron was also found. Boiceville is 615 feet A. T\, and this quarry is 
approximately 850 A. T. 
Cushley quarry, No. 1489 B3, is on the south side of Cold Brook 
Mountain. The stone is principally a massive, bluish-gray sandstone. 
There are also layers of pinkish stone, which make a good thin flagging, 
and near the middle of the ledge is a shaly layer with some clay peb- 
bles. The stone has a rather greenish matrix which weathers to a 
brown. There is a dip of between 5° and 6° between west and north- 
west. On the outcrop of one of the old quarries, a little farther north, 
an occasional white quartz pebble, with the clay pebbles, was seen. 
These quarries also have plenty of red shale and reddish sandstone. 
The altitude of this quarry is approximately 1,350 feet A. T,
