Kokanee Glacier 2021: slash and burn
By Ben Pelto, PhD, UBC Mitacs Elevate Postdoctoral Research Fellow Since 2013 I have been working on the Kokanee Glacier. Located just outside of Nelson in southeastern British Columbia (BC), the Kokanee Glacier is due north of the Washington-Idaho border. This work began as part of a five-year study of the cryosphere in the Canadian portion of the Columbia River. This project was carried out by the Canadian Columbia River …

Art and Science on the Easton Glacier: Reflections from the NCGCP 2020 Field Season
By: Cal Waichler, Jill Pelto, and Mariama Dryak. It is the evening of Aug. 9th, 2020 and six of us are camped near the terminus of Easton Glacier. The sun has dropped below the moraine ridge above camp and a chilly breeze has forced us to put on layers. We are enjoying dinner cooked on our camp stoves, discussing what we observed on the ice today. The toll of climate …

AGU Poster Hall-Cryosphere Perspectives
The American Geophysical Union Fall meeting’s Cryosphere section continues to grow as seen in the Poster hall. The poster hall is where most of the research is presented and is dominated by student work. Here are some examples of this work. Erin McConnell, UMaine and others examined shallow ice cores from glaciers in the St. Elias Mountains of Canada’s Yukon as part of a project to reconstruct past climate variability …

A Voice for Glaciers at COP21
During the last six years From a Glaciers Perspective has published 520 Posts examining the response of glaciers to climate change. No hyperbole has been needed to use words such as disappear, fragmented, disintegrated, and collapse. Glacier by glacier from the fragmentation of glaciers to the formation of new lakes and new islands has emphasized the changing map of our world as glaciers retreat. The story details change, but the story …

Index of Glacier Posts June 2009-June 2011
Glacier Index List Below is a list of the individual glacier posts examining our warming climates impact on each glacier. This represents the first two years of posts, 115 total posts, 108 different glaciers. I have worked directly on 34 of the glaciers described below. Other glaciers were selected based on fine research that I had come across, cited in each post, I then look at additional often more recent …

Gilkey Glacier Ogive Spacing and Retreat
The Gilkey Glacier is a 32 km long outlet glacier flowing west from the Juneau Icefield. From 1948 to 1967 the Gilkey Glacier retreated 600 m and in 1961 a proglacial began to form. By 2005 Gilkey Glacier has retreated 3900 m from the 1948 terminus location. USGS map of Gilkey Glacier from before lake formation. Google Earth of the developing lake. The glacier is currently terminating in this still …

Llaca Glacier Retreat, Peru
The Cordillera Blanca, Peru has 27 peaks over 6,000m, over 600 glaciers and is the highest tropical mountain range in the world. Glaciers are a key water resource from May-September in the region, Mark (2008). The glaciers in this range have been retreating extensively from 1970-2003, GLIMS identified a 22% reduction in glacier volume in the Cordillera Blanca. Vuille (2008) noted that the retreat rate has increased from 7-9 meters …

Stephenson Glacier retreat, Heard Island
The Australian Antarctic Division manages Heard Island Island and has undertaken a project documenting changes in the environment on the island. One aspect noted has been the change in glaciers. The Allison, Brown and Stephenson Glacier have all retreated substantially since 1947 when the first good maps of their terminus are available. Fourteen Men by Arthur Scholes (1952) documents a year spent by fourteen men of the Australian National Antarctic …

Ried Glacier Rapid Glacier loss, Switzerland
Ried Glacier is beneath the Durrenhorn in the Pennine Alps of Switzerland. The glacier was 6.3 km long in 1973. In 2010 the glacier is 5.1 km long. From the Swiss Glacier Monitoring Network annual measurements, Ried Glacier retreated 300 m from 1955-1990, 8 meters/year. From 1990-2008 retreated an additional 300 m, 30 m/year. Than in 2009 the glacier retreated 500 m. A comparison of a 2004 image taken by …

Lemon Creek Glacier Retreat Juneau Icefield Alaska
Above is a paired Landsat image with 1984 left and 2013 right, indicating a 300 m retreat in this interval. Annual balance measurements on the Lemon Creek Glacier, Alaska conducted by the Juneau Icefield Research Program from 1953 to 2013 provide a continuous 61 year record. This is one of the nine American glaciers selected in a global monitoring network during the IGY, 1957-58 and one of only two were …
