Name
The name was formerly written Ångermann or Angermann. The name is derived from the Old Norse anger, which means "deep fjord" and appears in placenames in Norway, and as "ånger" in placenames along the coast of Norrland.
Elk Migration
Every spring, the span of the river is host to an annual northern migratory crossing by hundreds of thousands of elk known as the Great Moose Migration or Great Elk Trek. More than 95% of the country's 300,000 elk are thought to migrate each year. Since 2019, the event has been livestreamed by Sweden's national broadcaster SVT. The village of Kullberg, on the western bank of the river, is a major source of footage for the livestream's channel. As of April 2025, a Facebook group devoted to the livestream had amassed more than 77,000 members.
