DESCRIPTION: 
Barrows, et al. 2001 geomorphic mapping and exposure dating via 10Be 
of late Pleistocene Australian mainland glaciation.  

Abstract:
Late Pleistocene glaciation of the Australian mainland was restricted 
to a small area of the southeastern highlands. Geomorphic mapping 
of the area and exposure dating using the in situ produced cosmogenic 
isotope 10Be provides evidence for at least two distinct glaciations. 
The Early Kosciuszko glaciation consisted of a single glacier advance 
before 59,300 ± 5400 years ago (Snowy River Advance). The Late Kosciuszko 
glaciation comprised three glacier advances 32,000 ± 2500 
(Headley Tarn Advance), 19,100 ± 1600 (Blue Lake Advance), and 
16,800 ± 1400 years ago (Mt. Twynam Advance). The Early Kosciuszko 
glaciation was the most extensive and the Late Kosciuszko advances were 
progressively less extensive. These periods of glaciation in the highlands 
correspond to episodes of periglacial activity and peaks in lake levels 
and river discharge at lower elevations in southeastern Australia. 
Glacier advances on the Kosciuszko Massif correlate with advances in 
Tasmania, South America, and New Zealand and are broadly representative 
of hemispheric climate changes during the last glacial cycle.
