Late Holocene Glacial Geomorphology and Sedimentology of Portage Glacier, South-Central Alaska

This study investigates the genesis of Little Ice Age glacial landforms present in Portage Glacier, south-central Alaska. Using till macrofabric and grain size analysis, this research tries to identify till types present in moraines and other glacial landforms in order to determine their depositional environment and landform classification. Basically, this research focuses on reconstructing paleo-glacial processes.
