ALTAMAHA GRIT REGION OF GEORGIA 



45 



The surface soil is usually of the Columbia sand, but never too 

 deep for the roots of trees to penetrate it into the Lafayette below. 

 The Lafayette is also so sandy on these ridges, however, that it 

 seems to make little difference to the vegetation whether the 

 Columbia is present or not. Lack of shade is a prominent char- 

 acteristic of this as well as several of the other habitats.
