The Barnes Ice Cap is an ice cap located in central Baffin Island, Nunavut, Canada.
Geography
[edit ]It covers close to 6,000 km2 (2,300 sq mi) in the area of the Baffin Mountains. It has been thinning due to regional warming.[1] Between 2004 and 2006, the ice cap was thinning at a rate of 1 m (3 ft 3 in) per year.
The ice cap contains Canada's oldest ice, some of it being over 20,000 years old.[2] It is a remnant of the Laurentide Ice Sheet, which covered much of Canada during the last glacial period of the Earth's current ice age.[3] Generator Lake is located at the southeastern end of the ice cap.[4]
