A '''[[glacier]]''' is a persistent body of dense [[ice]] that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating [[crevasse|crevasses]] and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines.

During this expedition, Blackburn and 41 other explorers were forced to winter over in the Little America base due to their ship being stuck in the pack ice.

Therefore, monitoring sea level rise and the mass balance of ice sheets and glaciers allows people to understand more about global warming.

Quin Blackburn was a geologist on the First and Second Byrd Expeditions and leader of the geologic party that explored the Transantarctic Mountains. Blackburn served as a geologist and seaman—before—the mast on the First Byrd Expedition (1928-1930). During this expedition, Blackburn and 41 other explorers were forced to winter over in the Little America base due to their ship being stuck in the pack ice.
