Fails mollic epipedon (ST) and mollic horizon (WRB) criteria either due to thickness (1994 pedon) or a structureless state (massive) and very hard rupture resistance when dry. If a mollic is recognized, the ST subgroup changes to Aquertic Hapludolls (and minus calcareous class) and the prefix qualifiers change to Mollic Gleyic for Fluvisols reference soil group in WRB. 3.)
