Cortland is kind of an interesting metropolitan area to explore, as the city is pretty much limited to the valley within the hills, as terrain and the lack of industry have limited it's growth. Outside of the city, is high, tree-covered hills and state land with shallow soils, and deep, rich agricultural valleys, especially to the north around Preble.

Believe it or not, water from Cuba Lake in Allegheny County NY flows to the Orleans Creek, Allegheny River, Ohio River and ultimately the Mighty Mississippi River down by New Orleans to the Gulf of Mexico.
After you head west from Kueka Lake, you enter hill and hollow country like you see in Madison County. Much bigger hills and aggressive terrain elevation changes once you get west of here.
I've long had a fascination with land use, elevation and contours. Looking north on Schoharie Valley into the Mohawk Valley with the Adirondacks in the distance.
