Type: Quarry.

Features: Non-marine to marine transition of the Catskill Clastic Wedge;
Rare ripple cross-lamination; sparse fossils(Sphenotus, fish plates, plant fragments).

Feature Type: Stratigraphic.

Reference: NYS Geological Association Field Trip Guidebook, 63rd Annual Meeting 1991;
Storm-Dominated Shelf and Tidally-Influenced Foreshore Sedimentation, Upper Devonian Sonyea Group,
Bainbridge to Sidney Center, New York. For Online Reference Please visit: - www.nysga.net/Guidebooks.html

Quadrangle: Unadilla.

Reason for Designation: The suspected oxisol profile at the Steele Residence
Quarry is not known to occur outside this study area in NYS. The oxisol is believed to
be unique within NYS because development of large, long-lived interfluve areas where
tidal processes dominated has not been documented elsewhere in the state. Cattarugus Magnafacies
rocks of this kind have not been described elsewhere in NYS. Sedimentary structures are displayed in dramatic fashion.
