Description Date: Jun 24 2014	State: Kansas
Describer: J. Anderson, B. Wehmueller, A. Baldwin, C. Remley	County: Riley
Site ID: S2014KS161502	MLRA: 76 -- Bluestem Hills
Site Note: This site is the representative soil for the NEON instrumentation located in the Konza Prairie Biological Experiment Station and represents the sites that will have instrumentation installed.	Soil Survey Area: KS161 -- Riley County, Kansas 5-SAL -- Salina, Kansas
Pedon ID: S2014KS161502	Map Unit: 4625 -- Dwight-Irwin complex, 1 to 3 percent slopes
Pedon Note: There was weathered limestone being exposed just below 2 meters. This is likely the Schroyer Limestone member of the Wreford Limestone formation in the Chase Group. The lithologic discountinity at 132 cm is based on the chert fragments in the material that appears to be reworked loess. This site is a taxadjunct to Konza since it has a clay decrease and won't meet the "pale" requirements.	Quad Name: Swede Creek, Kansas
