Tumbling soils have clayey particle size control sections. Clymer, Lehew and Wallen soils occupy similar landscape positions. The Jefferson, Nolichucky and Tumbling soils occupy side slopes and footslopes at relatively lower landscape positions. Permeability is moderate. Nearly all areas of these soils are in woodland.
Native vegetation consists of dominantly mixed hardwood species.
The series is of small extent. Name is from Baileys Gap, Virginia. These soils formerly were included in the Lehew series in Giles County but lab data show that these soils have an argillic horizon and have siliceous mineralogy.
