Accumulation of Peoria Loess coincides primarily with \nthe last glacial period, although accumulation was not synchronous across \nthe entire mid-continental region. The maximum-limiting of Peoria Loess \nrange from approximately 30-34 ka (organic matter from the uppermost \nRoxana Silt and Gilman Canyon Formation) to 20-22 ka in other regions.  \nThe actual time period of deposition varies from region to region \n(see e.g. Muhs and Bettis, 2000; Bettis et al., submitted).\n\nAlthough a map of loess thickness across the mid-continental USA has \nbeen made (Thorp and Smith, 1952; republished in generalized form by \nRuhe, 1983), this compilation is now more than 50 years old and has \nnever been assembled as a digital data set, allowing for a \nrepresentation of loess as a geomorphological feature that can be \ndirectly compared with regional model simulations over North America. \nThe purpose of digitizing loess thickness is to provide this information \nas part of the DIRTMAP data base (Kohfeld and Harrison, 2001), \nto demonstrate spatial changes in accumulation across the \nmid-continental USA, and to make it available to the geomorphology, \nQuaternary and earth system modeling communities.","version":"1.0","xmlId":"2678"}
