According to Michael Coughlan, our resident science guy and a teacher at the NYC Lab School for Collaborative Studies, we found a lot of Manhattan schist: the metamorphic layers give it an
orientation and often a long thin geometry which makes it fun for
landscaping. The mica crystals glisten in the sun. He tells us the larger rocks may have been glacial deposits. The smooth geometry and large size make for fun landscaping as well. We saw lots of worms in the soil and not as much clay or brick as we had feared. The soil seems quite organic.
