Long-Term Ecological Research (LTER) /NWTablatraw.td: Snowpack ablation in alpine couloirs: Raw data

For a more detailed metadata record, see: portal.edirepository.org/nis/metadataviewer?packageid=knb-lter-nwt.126.4 Lowering of the snowpack surface by ablation (melt) was measured on a bimonthly basis within couloirs above the Green Lakes and Isabelle Valleys during the summer months. The Niwot Ridge LTER site (40deg.3'N. 105deg.36'W.) is located approximately 35 km west of Boulder, Colorado, with the entire study site lying above 3000 m elevation.

There is a cirque glacier (Arikaree Glacier [~90K photo and caption]), extensive alpine tundra, a variety of glacial landforms, glacial lakes and moraines, cirques and talus slopes, patterned ground, and permafrost. The research area is bounded on the west by the Continental Divide, with runoff on the two sides being destined for the Colorado and Mississippi Rivers.
