What is Greywacke?
ROCK-Any of various dark gray, coarse-grained sandstones that contain abundant feldspar and rock fragments and often have a clay-rich matrix. Greywackes are thought to originate in environments where erosion, transportation, and deposition happen so quickly that minerals and rock fragments do not have sufficient time to break down into finer constituents.

The foundation of the farmhouse is built from this "Grafton Greywacke" and has been in place since 1845...
We have placed several large Greywacke boulders around our grounds for future generations to enjoy...
