Wally, we also got red soil, lots of clay and silt. It's not very good though, compacts too much and not very good texture in general. Not volcanic, I think the red color in ours may just come from high iron content
Areas of dense vegetation add organic material that adds up and over time break down the clay and you can actually find really good,rich,fertile soil but mainly in small pockets. Gotta try to look for indicator plants to find the right soil. Might find beautiful soil, then 10 yards away it's straight clay,silt,and sand.
The straight red clay soil though, that looks like your soil does, is about worthless on it's own. If you ammend with 50% organic material like compost, and add a bunch of lime it's actually not bad though, holds moisture alright too.
