CHEMUNG GROUP.

are almost innumerable. There are a few points, however, where observations can be much 
better made than at others, and where the different characters of the rocks and their contained 
fossils can be more readily examined. 
Along the eastern side of the district, the Inclined plane of the Railroad at Ithaca, and the 
Cascadilla and Fall creeks are the best localities for the lower part of the group. Farther 
south, the banks of Cayuta creek, and the lateral ravines joining the same, offer good expo¬ 
sures of the middle and higher parts of the group, with numerous fossils not seen at the more 
northern localities. 
At the Chemung Narrows (see sketch at the head of the group), in the town of Chemung, 
there is a very good exposure at a cliff upon the river bank, and the artificial excavation for a 
road has much increased the value of this locality. Some of the quarries near Elmira are of 
interest, but the exposures extend only to a few feet in depth. The hills in the vicinity of 
Bath offer many interesting localities, and some fossils not elsewhere seen. At Painted-post, 
along the excavation of the Blossburgh railroad, the strata are well exposed, and contain nu¬ 
merous fossils. This is one of the most interesting localities in that part of the State, and 
presents some features of the strata not so well exposed elsewhere. 
On the Genesee river, and in the banks of its tributary streams, there are several points of 
great interest. The most northerly of these is Caneadea creek, where there is a great ex¬ 
posure of green shale, with sandstones towards its termination. At Rockville on Black creek, 
there is an exposure of green shale, becoming olive on exposure, which contains an abundance 
of organic remains, and among these are several which have not been seen at any other lo¬ 
cality. In the creek at Hull’s mills near Angelica, there is a good exposure of shale and 
sandstones with some fossils. At Hobbieville and Phillipsburgh, a few miles farther south, 
we find an association of strata very similar to those of Rockville, and many of the same 
fossils, together with numerous other species. This neighborhood is one of the most prolific 
localities of fossils in the group, Farther south, at Vandemark’s creek, some of the higher 
strata, loaded with a large Delthyris, are well exposed, and fine specimens can be obtained. 
At Wellsville, a few miles south of the latter point, the rocks of this group terminate, and are 
succeeded by some thin ferruginous strata of the Old Red sandstone, and this again by grey 
diagonally laminated sandstone and conglomerate. 
In Cattaraugus county, there are good opportunities of examining the strata, at Bailey’s in 
the town of Leon, two or three localities near Cadiz, and in the southern part of Great-valley. 
The ravines on the south side of the Allegany expose the strata in numerous places, but there 
are few points where fossils can be obtained. 
In Chautauque county, the deep ravine of Chautauque creek affords the best opportunity of 
investigating the rocks of this group, which there contain numerous fossils. The outlet of 
Chautauque lake at Dexterville also affords a good opportunity of examining the strata, which 
in some parts are loaded with fossils. 
The localities enumerated are sufficient for a thorough investigation of the group; those 
upon the Genesee alone afford a very good exposure for a single line of section, but, as before 
remarked, there are many variations <?f character in an east and west direction, which present
