The soils formed under forest vegetation from Late Wisconsin glacial till in Northcentral Iowa were classified, according to the summary by Brown (1936), chiefly with the Conover series. In the soil survey of Story County, similar soils were classified with the Ames and Lindley series according to Meldrum, Perfect, and Mogen (1941). The Ames series is a Planosol formed under forest vegetation and occurs on nearly level to slightly level areas. As the Lindley soils occur principally in the Kansan till area, they include soils with ferretto-like profiles. Thus, it seemed desirable to introduce a new series for most of those soils classified as Lindley in the Story County soil survey and for the sloping soils mainly classified as Conover in Boone County. Therefore, the Hayden series, originally established in Minnesota as the Gray Brown Podzolic correlative of the Clarion series, a Brunizem, has been introduced into Iowa as has been discussed by Simonson, Riecken, and Smith (1952). This paper is a report of a study of two Hayden profiles, with a discussion of its relationship to the Clarion series and also to some other Gray Brown Padzolic series.
