Alaska Science Forum: A wrinkle beneath the icy face of Alaska
Scientists with the Alaska Earthquake Center created this diagram in which red dots represent the Dec. 6, 2025, Hubbard Glacier earthquake and its many aftershocks. The dotted line connecting the Totschunda and Fairweather fault systems represents a possible “connector fault,” about which scientists have theorized for years. (Graphic courtesy Alaska Earthquake Center) By Ned Rozell A few days ago, the forces beneath Alaska rattled people within a 500-mile radius: A magnitude

Alaska Science Forum: As the dark season begins, more light
In review: Green auroras occur at about 60 miles above Earth. Red auroras are much higher, from about 200 to 300 miles up, which allows people closer to the equator to see them. An important gas remaining at that altitude is oxygen; electrons that excite the oxygen atoms there produce red light.

Alaska Science Forum: The war within the aspen leaves
The caterpillar stage of the aspen leaf miner feeds on a leaf. (Photo by Ned Rozell) On one of the friendliest platforms imaginable, a ferocious battle rages. While mowing its way through the surface of a trembling leaf, an aspen leaf miner meets one of its kind. Instead of offering a nuzzle of recognition, the tiny caterpillar tears into the other with its sickle-like mouthparts, while trying to avoid a fatal gash from the other.

Alaska Science Forum: The secrets within Hummingbird Lake
Ancient pollen grains and other plant remains found deep within Hummingbird Lake in Southeast Alaska give clues to its unglaciated past. This photo is of a similar lake in Southeast Alaska. (Photo by Ned Rozell) Southeast Alaska is home to more than 850 species of native trees, shrubs and wildflowers. When you count them up, it’s more than half of all the plant species in Alaska, growing in just six percent of the state’s area. Glacial ice smothered most of the area not too l
