Biosketch

     I am interested in a variety of geomorphological and glaciological problems. An early and continuing curiosity about deposition on alluvial fans, and playas in arid regions led me to studies of the affect of recent tectonic movements on pluvial lake shorelines and on depositional patterns on fans. In the general area of fluvial geomorphology, I conducted a laboratory study of the mechanics of flow in meander bends. Most of my research, however, has been in the field of glacial geology and glaciology. My early work in this area was on Barnes Ice Cap on Baffin Island in the Canadian arctic where I studied the mechanics of moraine formation at the margins of polar ice sheets and the temperature distribution and deformation in such ice sheets. Between 1981 and 1995 I directed a glaciological research program on Storglaciären  in northern Sweden, focussing on the effect of subglacial water pressure variations on glacier dynamics and on subglacial till deformation. I've also done some 'ballpark' calculations on the role of humans in shaping the landscape.

     Presently (December 2012) I am mapping river terraces in Maine, and working on two papers, one on ore plumes in till and the other on the broad-scale topography of Maine 400 my ago based on pressures of crystalization of igneous and metamorphic rocks.  On the back burner are projects (1) on the relation between crustal structure and tilting of shorelines of glacial lakes in New England, (2) on modeling a glacier outburst flood on teh Arkansas River in Colorado , and (3) on the formation of glacial flutes.

      I am doing some teaching and enjoy interacting with students on their projects when I can be of assistance. However, I am no longer accepting new students as I am officially retired and am not sure how much longer I will continue working.
