Y‘* Black argillaceous shales nearly to the head of 
the creek. 56=383 
Y® Partly covered, but in the upper part at the 
head of the glen are iron-stained shales which weather 
yellowish and are somewhat transitional from the 
Utica to the Hudson river. * 19==402 
Y® Mostly covered in the field southeast of glen; 
sandstone in terrace at top which is perhaps not in 
place. 19421

On the western side of Bean hill the contact of the Utica slate 
and Hudson river formation is shown on the Charles Overbaugh 
_ farm in a gully on the northwestern side of the highway a short dis- 
tance south of the house. There is a pominent sandstone stratum 
just below the road below which are black argillaceous and calcare- 
ous shales. Mr Fisher found this black shale for 50 feet below the 
sandstone some of the joints in which had been filled with calcite; 
but saw no indications of sandstones or arenaceous shales. Again 
in the gully by the house on the south side of the highway is 
another exposure of the contact of the black Utica shale and Hud- 
son river sandstone. The black carbonaceous shale is shown in 
the run about opposite the house, and a little higher is a heavy 
sandstone stratum. 
Swartstown creek section 
An excellent section from the upper part of the Calciferous sand- 
rock through the Trenton formation to the base of the Utica slate, 
is that along Swartstown creek on the south side of the Mohawk 
river about three fourths of a mile below Crane’s village. This 
section is an interesting one to compare with the one already 
described opposite Crane’s village.!
