Abstract
On the southern Fraser Plateau an erosional corridor contains both hummocks and an esker. Ground-penetrating radar (GPR) data reveal that the erosional corridor is eroded into till and filled with broad deposits that are overlain by the esker. Slump blocks from the esker flank cap the fill. These data suggest five phases of erosional corridor development: 1) subglacial erosion of the corridor; 2) subglacial deposition of gravel sheets; 3) subglacial deposition of a corridor-wide gravel dune field; 4) esker deposition; and 5) postglacial esker reworking. These data suggest the erosional corridor was filled by high magnitude, bankfull flow and operated as a tunnel channel.
