Abstract

A detailed study of the surficial sediments and landforms in the lower Seymour Valley has provided a complete record of the last glacial cycle. This study shows that the valley was slowly aggrading before 29 ka and rapidly aggrading after 29 ka. Ice of the Fraser Glaciation reached the mouth of the valley about 22 ka and retreated before 18.5 ka. The valley was subsequently vegetated. Ice once again advanced and occupied Seymour Valley after about 17 ka. Before 11.5 ka ice in Seymour Valley retreated a final time, and the valley once again became vegetated.
