经过冰期晚期的推进,阿根廷巴塔哥尼亚的冰川迅速消退,到公元前10,000年,至少有一个冰川比现在大一点。冰河时代后的三个时期,第一次在亚北纬时代早期的4600年前达到顶峰,第二次在亚大西洋时期的2000年前达到顶峰,第三次在最近几个世纪。与世界上大多数其他地区不同的是,就目前所知,没有冰川在最近几个世纪达到冰期后的最大值。
After a late-glacial readvance, the glaciers in Argentine Patagonia receded quickly, and by 10,000 B.P. at least one glacier was little larger than it is today. Three episodes of postglacial readvance followed, the first culminating about 4600 B.P. during early Sub-Boreal time, the second about 2000 B.P. during the Sub-Atlantic, and the third during recent centuries. In contrast to most other parts of the world, no glacier, so far as is known, reached its maximum postglacial extent in recent centuries.
