The Columbia Icefield was one of the last major geological features in western Canada to be visited and recorded by Europeans, due to its isolation and harsh weather conditions. Glacier Recession and the Response of Summer Streamflow in the Pacific Northwest United States, 1960–2099. 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).
