Climate
East-Quincy is underlain by metasedimentary rock of the Shoo Fly Complex. Its dominant silica-rich clastic material weathers to a stony coarse soil which includes the well or somewhat excessively drained alluvial fan material (mainly Forgay very gravelly sandy loam) on which most of Quincy's businesses and homes have been built. Cultivated land north of the residential area lies on poorly drained loam, silt loam or fine sandy loam.

Although summer days are hot and only 1.4 days per winter fail to top , nights can be very cold and frosts occur on 179 days per year and have been recorded even in July.
