San Quint穩n Glacier is situated within Laguna San Rafael National Park and drains west toward the Pacific Ocean. The terminal end of the glacier (left in this image) meets a lake that gets its beige color from glacial flour - the pulverized rock that is ground up by the moving ice. Hundreds of icebergs surround the glacier's end, while a stream flows west toward the Golfo de Pe簽as on the Pacific Ocean. The Northern Patagonian Icefield in the Andes Mountains in Chil矇 is a remnant of an ice sheet that covered the region about a million years ago. Though much smaller today, it is still one of the largest temperate (mid-latitude or non-polar) icefields in the world. Twenty-eight exit glaciers flow out of that field, and San Quint穩n is the largest. Scientists have been monitoring San Quint穩n, nearby San Rafael, and other glaciers in this icefield because they appear to be losing a significant amount of mass.
