History

Quincy is on the current and ancestral lands of the Maidu people. Quincy started as a Gold Rush town, associated with the former Elizabethtown, California. Started in 1852, Elizabethtown slowly faded.

Development moved a mile away into the American Valley after settler James H. Bradley, who helped organize Plumas County, donated land there for the county seat. He laid out the town and named it after his farm in Illinois that had been named for John Quincy Adams (1767–1848), the sixth president of the United States (1825–1829).

The Quincy post office opened in 1855, and the town was formally recognized in 1858.

Geography

Quincy is located at 39°56′11″N 120°56′53″W / 39.93639°N 120.94806°W / 39.93639; -120.94806 (39.936279, −120.947921).

According to the United States Census Bureau, the CDP has a total area of 4.2 square miles (11 km), all of it is land.

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.

Quincy has a Mediterranean climate (Köppen Csb) though its inland location and altitude makes it more continental and wetter than usual for this type, with very heavy snowfalls sometimes occurring in winter – the record being 133 inches (337.8 cm) in the very wet January 1916. Although summer days are hot and only 1.4 days per winter fail to top 32 °F (0 °C), nights can be very cold and frosts occur on 179 days per year and have been recorded even in July.
