Thanks to JUNGLE J for sending me this gem from a 1967 Ontario Department of Mines publication called " Geology and Scenery-Peterborough,Bancroft, and Madoc Area ." 2018-02-22 · The classic drumlin shapes is a hill that highest on its up-glacier end and tapers gently from there, like a half-buried egg. Not all drumlins taper like this, though. Because they have been streamlined by flowing ice, scientists often use them to understand past glacier flow directions. They are longest in the direction of flow. Eskers are the structures formed when the glacial meltwater carried the sediments and deposit it in subglacial tunnels, therefore they can provide vital information about the dynamics and shapes of ice sheets and glaciers whereas, Drumlis are formed when the ice sheets move in streamline over the rock debris. What are Eskers, Drumlins, and Moulins? Eskers - Ridge of till forming where a glacial meltwater tunnel once was, as the meltwater decreased as the glacier retreated the meltwater channel was unable to suspend the till and it gets deposited.

‘About 10,000 years ago, boulders and soils trapped beneath retreating ice sheets were moulded into drumlins, and it is believed there is an island for each day of the year.’ ‘A large interior plateau contains dense forests, thousands of lakes and peat bogs, and rocky infertile soils associated with a glacially modified landscape with numerous drumlins and eskers.’
