When we were young we thought the landscape told the truth

 

 When we were young we thought our town, Chappaqua, was the center of the universe,

and nearby Katonah, a dull burg on a hillside north of nowhere.

 Katonah used to be a river town where the Cross River ran into the Croton river. 

 The New Croton Dam changed everything.

Croton River valley flooded for over 20 miles. Over 150 farms were drowned.  

The houses of Katonah jumped up

and ran 

for the hills
