Summary:

Pg. 12 (fig. 5), 15. Atchison formation. Consists of well-sorted sand and silt with sand and gravel at base; commonly thinly laminated in upper part. In Atchison County, Kansas, has a maximum thickness of 80 feet; commonly 40 feet thick. Not recognized beyond the limits of Kansan glaciation. Overlies Nebraska till; underlies Kansas glacial till. Comprises pro-Kansas outwash of early Kansas age. Age is Pleistocene. Report includes columnar section.
Named from exposures in the vicinity of Atchison, Atchison Co., northeastern KS.

Summary:

(Cenozoic Era; Quaternary System by C.K. Bayne and H.G. O'Connor, p. 60 (table 3), 63.) The Atchison Formation is a proglacial deposit which is not recognizable beyond the limits of Kansan glaciation. It is composed of fine-grained sand and silt and locally gravel at the base. The upper part is thinly laminated. Similar deposits occur between the Cedar Bluffs and Nickerson tills. The maximum known thickness is nearly 100 feet, but it is commonly less than 40 feet thick. Occurs above Afton soil and below Nickerson till (p. 60, tbl. 3). Age is Pleistocene (Kansan).
