Abstract
An exposure in one of a series of small end moraines is described. The deposits are of late Pleistocene age and were laid down during the retreat of the glacier that occupied the Lake St. Clair trough, west-central Tasmania. The moraine is composed of beds of gravel, sand, clay, and massive silts up to 3 feet thick, capped with bouldery till. The beds, which dip upstream, show only localized slump structures. Together with the presence of undisturbed false bedding in the gravels, this structure suggests that the englacial relationships of the deposits have been preserved. An origin by slow melting of debris-charged ice is suggested.
