Ichnofossils (burrow casts) and fossils from an extinct form of prairie dog, Cynomys niobrarius churcherii, in the Hand Hills of south-central Alberta, have provided an important Late Pleistocene stratigraphic marker. The marker fossils provide relat

Contemporary processes of moraine development at the margins of polar glaciers encompass a wide range of subtly different mechanisms. Two types of “controlled” moraine evolution, applicable to hummocks and transverse moraine ridges, are identifie

During part of the late Pleistocene period distributary ice from the Rakaia Valley glaciers flowed into the High Peak Valley. Little evidence remains as to the extent of the Woodlands glacier within this area, but the Tui Creek glacier limits are wel
