Geologic Structure and Occurrence of Gas in Part of Southwestern New York: Part 1. Structure and Gas Possibilities of the Oriskany Sandstone in Steuben, Yates, and Parts of the Adjacent Counties

From introduction: Since the discovery of the Wayne-Dundee gas field in 1930 and the more recent discovery of large quantities of gas in the Oriskany sandstone about 2 miles north of the village of Greenwood the search for similar favorable structural features has been greatly stimulated in the Finger Lakes region and southwestward to the Pennsylvania line. To aid those interested in the area to gain a clearer understanding of the regional structure and its relation to the subsurface structure, parties in charge of the senior author were assigned during the field seasons of 1934 and 1935 to make a geologic study of Steuben County and parts of the adjacent counties.
