The river flows next to the Lowell glacier
Glacier
A glacier is a large persistent body of ice that forms where the accumulation of snow exceeds its ablation over many years, often centuries. At least 0.1 km² in area and 50 m thick, but often much larger, a glacier slowly deforms and flows due to stresses induced by its weight...

 which blocked off the river from 1725 to 1850 and created a large lake behind it. When the glacier broke in 1850, it created a massive flood, washing away everything in its path on the way to the Pacific.

The river carries a lot of silt from the Alsek lake/glacier, which contributes to the river's low temperature.

The Alsek and nearby East Alsek rivers were at one time connected, and the old river bed can still be made out on some maps.

The Alsek glacier contacts the Grand Plateau glacier, which faces the shoreline. Also in the same general area are the Doame foothills and Doame River.

History

. "This has been a day!," he wrote in his journal. "I want any other kayaker or would-be expert to read my words well. The Alsek Gorge is unpaddleable!" Despite this sincere warning from a man who apparently felt lucky to be alive, groups of expert kayakers have successfully run Turnback Canyon since then. A prominent mountain which overlooks the Alsek was named Mount Blackadar in his honor.

In 1958, a magnitude 7.7 earthquake centered near Lituya bay significantly changed the lay of the land. The earthquake caused the Doame River and East Alsek River to join together.

 can also be caught, but are not generally sought after due to their relative lack of worth/quality. These two rivers can be characterized as low volume fisheries, while the Alsek river in particular produces particularly high quality salmon due to its low temperature. The Alsek's silt content also prevents the sun from damaging the fish.

The area also supports subsistence and sport fishing. There are multiple local sport fishing, sight-seeing, hunting, and animal watching lodges
