As you can see on the map above, there are two types of rocks on the property.  The south end of the property is underlain by limestone while the north end of the property is underlain by "a purplish-red shale formation containing thin layers of limestone at wide intervals."

The two types of rock on the property result in very different types of soil, land forms, and plant communities in the two areas, each of which will be discussed in detail in a later section.  In general, the shale formation on the northern half of the property forms acidic soil while the limestone on the southern half of the property forms soil with a high calcium content.
