The glacial diversion of the Que and Bulgobac Rivers, western Tasmania.

Abstract

Glacier ice diverted the courses of the upper Que and Bulgobac Rivers from a direct route to the Pieman River through the Que Gorge to the Huskisson River. The diversion probably occurred in the Early Pleistocene but the drainage pattern established was maintained and perhaps accentuated by further glaciation during the Middle Pleistocene. The modern drainage pattern is a palimpsest of that which existed by late Middle Pleistocene times.
