The 0a horizons are commonly continuous vertically, but in some pedons there are alternating thin strata of organic material and marl. Some pedons have a thin Oe horizon. The 2C horizon is neutral, or has hue of 10YR through 5Y, value of 4 through 8 and chroma of 0 through 2, with or without mottles. It has granular or subangular blocky structure, or it is massive. Consistence is friable or firm.
Effervescence is strong or violent.
The 3C horizon, where present, ranges in texture from silty clay to sand. Consistence is very friable to firm. These are the Aurelius and Kjar series in the same family, and the Edwards , Rondeau and Warners series in related families. Aurelius soils have loamy substratum layers within a depth of 40 inches. Kjar soils are moderately or strongly saline.
