Lyell Glacier is no longer active, but McClure Glacier is still moving and has an ice cave at its toe that enabled the researchers to collect fresh polish from an area of active sliding and abrasion.

The low plam cuts across fjord deeps and corrie lake deeps, and though local glaciers have certainly played a notable part, it is in the main due to marine abrasion. Prof.

Abrasion – rocks trapped in the glacier rub against the valley floor wearing it away like sandpaper. Transportation. Eroded material, such as rock, is moved by the glacier.

Yet you might not know exactly how influential glaciers have been throughout geologic history is forming our landscapes. There are three distinct ways that glaciers shape the land: 1) erosion 2) ...

The banks of the St. Lawrence near Brockville, and all the Thousand Islands, have been rounded and montonnee by glacial abrasion during tlie period when all this mass of ice was moving southward ...
