We present a detailed study of landforms from Bourgeois Fjord to Marguerite Bay.

Landforms from the inner fjord (Blind Bay) to the shelf-edge are genetically linked.

The outer and main fjord underwent a relatively rapid and continuous deglaciation.

Blind Bay records recent glacial readvances, probably related to the Little Ice Age.

Tidewater glaciers have generally retreated in the last decades, but not homogeneously.
