Canadian Columbia Basin Glacier Spring 2016 Field Season (winter 2015-2016 Assessment)
Guest Post by Ben Pelto, PhD Candidate, UNBC Geography, [email protected] During the spring season we visited our four study glaciers (Figure 1), which form a transect of the Columbia Mountains from the Kokanee Glacier in the Selkirk Range to the south, to the Conrad (Purcells) and Nordic (Selkirks) in the center, to the Zillmer of the Premier Range in the north. This post will explore the snowpack of winter 2016 across …

Pacific Northwest Glaciers: Widespread early Melt Season Arrival
The 2016 melt season is off to an early start in Greenland, but this is not the only location. This winter proved to be warm, but relatively wet across much of the Pacific Northwest. A look at the average freezing level (determined by North American Freezing Level Tracker-Developed by John Abatzoglou and Kelly Redmond) from January 1 to April 20 indicates freezing levels well above average on Mount Baker …

Hess Mountain Glacier Retreat, Yukon
In the Selwyn Mountain Range, Yukon at the headwaters of the Hess River is the Hess Mountains and Keele Peake the highest peak in the region. A series of glacier radiate from this region. The Yukon Territory is host to numerous small alpine glaciers that have been rapidly losing area and volume. From 1958-2007 glaciers lost 22% of their volume in the Yukon (Barrand and Sharp, 2010). Due to the …
