Carpenter Hill from Virgil Road, Route 392, looking across cornstalk stubble and McClintock Road, a faded yellow barn with “Vinda Acres” written on the doors.

The hill is clearly a drumlin. A drumlin, from the Irish word droimnín (“littlest ridge”), first recorded in 1833, is an elongated hill in the shape of an inverted spoon or half-buried egg formed by glacial ice acting on underlying unconsolidated till or ground moraine.

Distant ridges on the right include Hammond Hill. The road to Virgil above the town of Dryden, Tompkins County, New York.
Would there be rocks deep underneath the soil of that drumlin?

It depends. Could be rocks, though most likely a combination of till, gravel and boulders. Till is sand, clay, silt with pebbles mixed in: the stuff carried by the glacier well mixed together and dumped where the ice melted.

Enjoy the setting! I like taking a drive to see the harvested fields of soybeans and corn as they rest until spring.
