Fraenkel Glacier Retreat, Patagonia, Chile

Fraenkel Glacier drains the west side of the Northern Patagonia Ice Cap (NPI) just south of Glaciar San Quintin. The retreat of this glacier in the last 30 years mirrors that of Gualas and Reichert Glacier, which also terminate in an expanding proglacial lake.   Davies and Glasser (2012) work, had an excellent Figure indicating two periods of fastest recession since 1870, are 1975-1986 and 2001-2011 for NPI glaciers.  They noted …

North Leones Glacier Retreat and new Landslide, Patagonia, Chile

Jill Pelto, my daughter returning from fieldwork with UMaine in the Falkland Island took a picture last week out the plane window of Leones Glacier of the northern Patagonia Icefield. The picture illustrated two changes worth further examination, and the fact that if you have a glacier picture that you would like more information on let me know. The picture indicates outlet glaciers of the Northern Patagonia icefield fed by …

Verde Glacier Retreat, Chile

Verde Glacier is adjacent to Reichert Glacier and drains the north side of the Northern Patagonia Icefield. It is a small glacier compare to many outlet glaciers of the icefield that have been examined in previous posts, Reichert Glacier, Steffen Glacier, Nef Glacier, and Colonia Glacier. Here we examine Landsat imagery during the 1998-2014 period to identify the response of the glacier. The glacier flows from a pair of peaks …

Glaciar Chico Retreat, Patagonia, Chile

Glaciar Chico drains the east side of the Southern Patagonia Icecap (SPI). Rivera et al (2005) noted that Glaciar Chico had retreated significantly from 1945 to 1976, calving into Brazo Chico, but then retreated slower than most SPI glacier from 1975 to 2001, second image from Rivera et al (2005). Davies and Glasser (2012). noted that Glaciar Chico’s thinning rates are comparable to other glaciers of the SPI, and the …

Glacier Noroeste Retreat, Gran Campo Nevado, Chile

The Gran Campo Nevado (GCN) is the smallest of the four primary Patagonian Icefields. It is on the Península Muñoz Gamero 200 km to the south of the Southern Patagonia Icefield. The major outlet of this icefield is the Noroeste Glacier. In a recent paper examining the changes in Patagonia glacier from 1870-2010 (Davies and Glasser, 2012), observed that the Gran Campo Nevado icefield lost of its area from 1870-2010, …
