The Penny Ice Cap is a 6,000 km2 (2,300 sq mi) ice cap in Auyuittuq National Park of Baffin Island, Nunavut, Canada. It forms a 2,000 m (6,562 ft) high barrier on the Cumberland Peninsula, an area of deep fiords and glaciated valleys. It is a remnant of the last ice age. During the mid-1990s, Canadian researchers studied the glacier's patterns of freezing and thawing over centuries by drilling ice core samples.
The ice cap has been thinning and its valley glaciers have been retreating in recent decades related to rising summer and winter air temperatures across the eastern Arctic.
