The document describes two soil series - Dayton and Bashaw. Dayton soil is classified as a fine, smectitic, mesic Vertic Albaqualf formed in silty and clayey glaciolacustrine deposits. It has a silt loam or silty clay loam texture. Bashaw soil is classified as a very-fine, smectitic, mesic Xeric Endoaquert formed in clayey alluvium derived from basalt. It has a clay, silty clay, or silty clay loam texture. Profiles and characteristics of each soil are provided.
