Quaternary strata in northcentral Missouri were deposited prior to, during, and subsequent to glaciation of the area. Major depositional units are separated by buried soils. The lower Quaternary Whippoorwill formation is derived from local bedrock and has the intensely weathered New Florence soil developed in it. The pre‐Illinoian McCredie formation, primarily till, is derived from distant shield and local cratonic rocks. The moderately weathered Kingdom City soil within the formation suggests that an intcrglacial separated two ice advances. The lllinoian Lovcland and Wisconsinan Peoria Loesses are derived from Missouri River outwash. Since glaciation, the welded Yarmouth‐Sangamon Soil has developed in till and in lllinoian loess on stable sites but middle and late Sangamon Soils have developed on erosional surfaces. Holocene soils are developed in Wisconsinan loess and alluvium‐colluvium.
