The balance trend for the higher altitude Thunder Creek glaciers shows a major change occurring about 1944, from generally negative balances between 1920-44 to a gain in glacier mass between 1945-65; 2. The study monitors climate, glacial movement, glacial runoff, glacier mass-balance, and stream runoff. Topographic maps of the glacier were made from late summer vertical aerial photography in 1958, 1961, 1964, 1977, 1980 and 1985. To arrive at optimal mass balance simulations, we investigate and quantify model uncertainty associated with selecting from a range of physical parameter values that are not commonly measured in glaciological mass balance field studies. - Full mass balance plot and other info.

Ettl David L. Peterson Don McKenzie Andrew Fountain Program Authorized to Offer Degree: School of Environmental and Forest Sciences. Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers. To test these hypotheses will require five years of detailed mass balance measurements on three glaciers in the North Cascades. A glacier has no memory of the past year when it comes to mass balance, unlike say the extent of sea ice, it is more like the extent of snowcover. The computed cumulative mass balance from 1970 to 1997 would have been 16% too negative if the 1970 map had not been updated. The North Cascade Glacier Climate Project measures the annual balance of 9 glaciers, more than any other program in North America.

Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers. Regional variation in glacier mass balance is due to variation in geo-graphic characteristics such as aspect, elevation and location with respect to prevailing winds. This glacier has been classified as one of the ‘reference glaciers’ by the World Glacier Monitoring Service because it has received continuous long-term observations dating back to the year 1952/53.
