Comments: In the description of CZph on the printed map, there is a unit called CZph1 and it applies to the hornfels of the Lilesville granite aureole. On the digital map this unit is NOT used, only CZph. So I did NOT make a separate unit for CZph1. The digital map DOES use the unit CZbg (which is described under CZph on the printed map also), so I DID make this a separate unit.
