Day 5 - Greenland Sea

Blue skies, sunshine and the occasional iceberg marked our progress south off shore from Liverpool Land. The rock units along the coast are some of the oldest in Greenland. They are mostly composed of Proterozoic gneiss and granite ranging in age from 1.2 to 2.0 billion years B.P. They provide a rugged backdrop for the alpine glaciers that carve arĂȘtes into the rock as they move down toward, and sometimes into, the sea.
