Since most of these glaciers reside west of the continental divide, the 2005 inventory identified only 1,167 glaciers in Alberta, covering an area of 786 km 2. and Alberta in 2005, covering 26,728 km 2. (2010) inventory estimates a total of 17,595 glaciers in B.C. It follows that the WC 2N inventory and glacier outlines are the best option for both spatial and temporal resolution, although it is not without some shortcomings. In comparison to the NRCan glacier layer, the WC2N outlines appear to be of higher resolution and have less smoothed borders. Two complete time slices have been compiled for the glaciers of Alberta and B.C. This dataset has been contributed as a public resource to the Global Land Ice Measurement from Space (GLIMS) glacier inventory. (2010) as part of the Western Canadian Cryosphere Network (WC 2N). The most recent and thorough inventory of glaciers in western Canada is the recently-completed compilation of Bolch et al. This means that the majority of glaciers in the interior ranges of western Canada are small and vulnerable to ongoing retreat. covered an area of 4,298 km 2, giving an average glacier size of 1.3 km 2. The compilation did point out some important statistics regarding the glacier size distribution: a total count of 3,271 glaciers in the Rocky and Columbia Mountains of Alberta and B.C. Many of the glacier outlines are therefore not representative of present extents and the temporal resolution can be considered poor. For instance, it was produced using maps ranging from 1969 to 1998, a period during which glaciers experienced extensive retreat. This glacier layer is also not without its problems. Glaciers from these maps were later digitized. In a subsequent effort, Natural Resources Canada produced 1:50,000 scale topographic maps of the Canadian Rockies. As the project came to a halt in 1974, glaciers north of the Nelson River Drainage basin were not counted or mapped. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.In total, the initial inventory found 1,524 areas of perennial snow and ice in the Nelson River catchment. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it.
