Abstract

Moraines on Schnells Ridge, southwest Tasmania, have been dated using in situ 10Be. An age of 19,400 F 600 yr is indicated for the wellpreserved
innermost moraine from consistent measurements on four large quartzite boulders. This corresponds closely with exposure ages
reported by T.T. Barrows et al. (2002, Quaternary Science Reviews 21, 159–173) for Last Glacial Maximum glacial features farther north in
Tasmania and southeast Australia. In contrast, ages between 39,000 and 141,000 yr were obtained from a series of boulders on a more
extensive outer moraine, indicating that this has had a more complex history.
