Glacio-dynamic variations in central New York drumlins: a morphometric analysis

M. Francek, R. Blish

Research output: Contribution to journalArticlepeer-review


Varying rates of till deformation as a function of surface topography and direction of continental ice advance are linked to pattern and form variations in drumlins. Five transects are examined morphometrically. Transects are selected on the basis of their slope and direction of ice advance. A hypothesis based on variable rates of clast lodgement and till deformation accounts for most of drumlins' spatial characteristics. The Cayuga Trough funnelled most of the ice southward and the large amounts of till mobilized contribute to high drumlin densities. The observed increase in drumlin elongation is linked to local ice surging. Away from the trough, drumlin densities and elongation begin to decrease. -from Authors
