*Talk Title*: Drumlins

*Abstract:* Drumlins are small rounded hills which occur in swarms, and
which are formed under ice sheets. They are ubiquitous  in North America
and Northern Europe due to the former presence of the great ice sheets of
the last ice age. The enigma of their formation has generated a rich
literature over the last two hundred years. The instability theory of
drumlin formation has its roots in the work of Richard Hindmarsh in the
late 1990s. His basic idea was that drumlins form through an instability
due to the shearing motion of ice flowing over a deformable subglacial
till. The ingredients of the theory are thus ice flow and till flow. Later,
water flow was added. The development of the theory beyond the basic linear
instability result was initially hampered by a catacomb of difficulties:
these include till rheology, two-dimensionality and cavitation.The
numerical solution of the model is also fraught with complication. In this
talk,  I will describe and illustrate their efforts to resolve these and
other difficulties as they arose over the course of the last twenty years,
and a summary of the way in which the theory needs to progress will be
outlined.
