The ensuing retreat of the Athabasca Glacier has continued except for brief standstills. The Athabasca glacier is receding extremely rapidly and has lost over 60% of its ice mass in less than 150 years. In fact, data studied between 2004- 2005 and 2005-2006 showed the average rate of thinning and melting of ice had more than doubled. In recent decades, the glacier's recession has varied, at times pulling back 500 feet in a single year. In addition, glacier meltwater carries and deposits debris, forming such features as deltas and glacial outwash plains composed of sand and gravel (see also Esker). Dating the Moraines and Recession of Athabasca and Dome Glaciers, Alberta, Canada. Results show that the rate of regional glacier recession will increase, but the runoff from glacier melt and its relative contribution to streamflow display both positive and negative trends.
