COMPETING SERIES: This is the Mattaponi series in the same family and the Cataula and Hard Labor series in a closely related family. Mattaponi soils are formed in Coastal Plain and fluvial sediments and Piedmont cappings and are not subject to seasonal flooding. Cataula and Hard Labor soils have kaolinitic mineralogy and are found on Piedmont uplands.

Altavista soils have a fine-loamy particle-size control section; on similar landforms
Wickham soils have a fine-loamy particle-size control section; on similar landforms
McQueen soils do not have a seasonal high water table within 40 inches of the soil surface; on similar landforms
Mattaponi soils do not flood; on convex upland divides
