The glacier isn’t surging right now, but it’s likely due to surge again soon – there were two instances in the past 100 years (1986 and 2002) when Hubbard Glacier blocked Russell Fjord from draining with its calving ice shards and advancing moraine. Rising water in the newly formed lake altered local hydrology and was a threat to nearby communities. Water flowing into the cutoff There could be short term benefits to the closure. The Hubbard Glacier is an active glacier with two major surges in the last 30 years, at one point advancing more than 7 feet a day. It has been growing and advancing over the past hundred years.
