Morphology of late Holocene soils at the Lubbock Lake archeological site, Texas.

Three soils have been identified in late Holocene deposits at the Lubbock Lake site, a well- stratified archaeological locality on the Southern High Plains. The Lubbock Lake Soil formed in material deposited between 5000 and 4500 yr BP and has had 4500 yr to form or, where buried, 3500 yr. The Apache Soil formed in sediments deposited from 800 to 450 yr BP and is 450 yr old where not buried and 200 yr old where buried. The Singer Soil formed in sediments deposited from 250 and 100 yr. BP, allowing 100 yr for soil formation. These late Holocene soils will be useful stratigraphic markers and dating tools. -from Author
