No, they are not all the same……
The point that I was trying to make, and failed, that it is a mistake to classify all soil groups as “East Texas”.
Imagine a “layer cake” of sedimentary rocks, subsequently eroded from hills to valleys, to river flood plains, changing one type to another.
“It all depends”
Soils weather from rocks…
Good question – thanks.
ps: not to further complicate matters, but a geologic cross section between N.E. to S. E. Texas, in addition to erosional and structural features, will demonstrate “increase in thickness and depth “down-dip”, changing from older surface to younger surface rocks, all deposited in shallow seas toward present day Gulf of Mexico.
