|Name||Nunda Formation, West Hill Formation|
|Geologic age||Upper Devonian|
|Original map label||Dwc|
|Comments||part of West Falls Group 1100-1600 ft. (340-490 m). Second description from USGS Lexicon website (ref. NY046) and reference NY020: In western NY, the Nunda Member of the West Falls Formation generally includes two packets of sandstone beds--one at the base and one near the top. Total number of sandstone beds varies from one to eight and total thickness varies from 0 to 38 m. Authors include in the Nunda the intertonguing shales of the Angola for ease of analysis. Unit is most likely a submarine fan deposit as the sandstones are generally thick, massive to wavy/flaggy-bedded, have few primary sedimentary structures, terminate abruptly, and appear to have lobate forms (Jacobi and others, 1994).|
