 of the glacier. The bulk of the glacier is part of the icefield plateau. It flows eastward into O'Higgins Lake and is about 2 km (1.2 mi) wide at the terminus.

The glacier is also known to be melting caused by Global Warming

Global warming

Global warming refers to the rising average temperature of Earth's atmosphere and oceans and its projected continuation. In the last 100 years, Earth's average surface temperature increased by about with about two thirds of the increase occurring over just the last three decades...
