62 PENNSYLVANIA AND NEW YORK DEVONIAN. [bull. 120. 
No. 1489 Al.— MOUNT PLEASANT. 
In a railroad cut three-fourths of a mile south of Mount Pleasant is 
a good exposure of chocolate-colored shales and sandstones. The shales 
are very argillaceous and contain the fucoid (?) markings so generally 
seen in the red shales of the Catskill region. The olive to greenish- 
gray coarse-grained sandstone also occurs in close connection with the 
red sandstone, as on the eastern side of the track at the south end and 
under the red. This may be regarded as a good exposure of the 
"Oneonta" reds. At one point in the cut is a dip of between 3° and 
4°, about 15° west of north, while at the southern end the dip is 3°, 
5° east of north, showing a small anticline in this cut. Mount Pleas- 
ant is 3 miles north of Boiceville, with an altitude of 700 feet, and the 
cut has an approximate altitude of 685 feet A. T. 
No. 1489 A2. — The Nelson Lane quarry is immediately above the 
southern end of the railroad cut just described. The stone is the dark, 
bluish gray sandstone, which is in layers of a foot or more in thick- 
ness, except in the upper part of the quarry, where there are layers of 
stone 3 inches in thickness that make good flagging. The expo- 
sure is 25 feet in thickness, the massive sandstone strata being sep- 
arated by shaiy layers, in which are clay pebbles; and in one of them, 
near the middle of the ledge, are numerous clay j>ebbles in association 
with an occasional white quartz pebble. Pieces of fossil wood and 
plant fragments are quite common, and one piece of Lepldodendron 
with clear markings was found. The greatest dip is toward the north- 
west, and the quarry is about 115 feet above the railroad, or with an 
approximate altitude of 800 feet A. T. There is a great deal of cross 
bedding in this ledge, similar to that figured by Vanuxem for the Cats- 
kill. 1 By the quarry road leading down the hillside, and a little lower 
than this quarry, is another opening in a similar sandstone, below which 
occurs the red shale and sandstone. 
PHOENICIA. 
No. 1490. — On the western side of the railroad, from Boiceville to 1 
mile north of Phoenicia, there is no break in the mountains, and at 
Phoenicia, where the Stony Clove Creek enters Esopus Creek from the 
northeast, the two valleys are very narrow witli steep mountain slopes 
on either side. This region forms a charming summer resort and is 
much frequented. Near Phoenicia on the sides of the steep mountain 
slopes are numerous ledges of grayish sandstone in which a number of 
quarries have been opened, and at present Phoenicia is one of the most 
important shipping points for flagging stone on the line of the Ulster 
and Delaware Railroad. 
No. 1490 Al.— The Baldwin quarry is on Mount Bonier, one-half 
mile southwest of Phoenicia. The stone is mainly a bluish gray saud-
