Black Rapids Glacier, Alaska
Black Rapids Glacier is a surge-type glacier which most recently surged in 1936-37 and is currently in its quiescent phase. While many glaciers in Alaska exhibit reoccurring surge behavior, this glacier is of special interest because it is a potential hazard to the trans-Alaska oil pipeline.
USGS studied Black Rapids Glacier, Alaska from 1970 to 1992 with observations of mass balance, ice velocity, glacier surface altitude, and ice thickness. Ten sites on the glacier were monitored from 1972 to 1987, and three sites were monitored from 1988 to 1992.
More recently, study of Black Rapids Glacier has been continued by the University of Alaska (see Martin Truffer under links below).
On November 3, 2002, the M7.9 Denali Fault Earthquake caused several massive avalanches onto Black Rapids Glacier. Three rock falls from the south wall of the Black Rapids Glacier covered about 13 km of the ablation area or about 5% of the total glacier area.
