 Gallupville, where the long, smooth ridges and boat-shaped troughs give a

The map shows the dominant elements of the physiography and the location of the 

 drumlin belt here described. The drumlin symbols indicate merely the general distri- 

 bution and the prevailing directions of the drumlins, not individual drumlins. Drumlins
