To the delight of the local mosquitoes, Nicholas Hasson steps through a tangle of prickly spruce branches while wearing a backpack that holds a scientific instrument. Hasson is walking as straight a line as he can through a Fairbanks subdivision built in the boreal forest. Hasson studies permafrost at the University of Alaska Fairbanks. He […]
I just so happened to be stretched out on good ol’ Mother Earth the other night when an earthquake happened. On a Memorial Day overnight canoe trip, a friend and I had dragged our boats onto the gravel of a little island on the Chena River. After mosquitoes chased us into our tents and we’d […]
On a fine June day about 100 years ago, in a green mountain valley where the Aleutians stick to the rest of Alaska, the world fell apart. Earthquakes swayed the alders and spruce. A mountain shook, groaned, and collapsed in on itself, its former summit swallowing rock and dust until it became a giant, steaming […]
Wolves with adequate social distancing from humans tend to avoid nasty viruses, scientists have found. In a study of more than 2,000 gray wolves from near Mexico to northern Canada, researchers found that the farther wolves were from people, the fewer viruses and parasites they encountered. In the study, scientists used blood samples taken over […]
In Alaska’s infinite waters swims a handsome, silvery fish. Until recently, we knew little about the Bering cisco, which exists only around Alaska and Siberia. Then a scientist combined his unique life experiences with modern tools to help color in the fish’s life history. Randy Brown is a fisheries biologist with the U.S. Fish and […]
High on the broken pyramid of Iliamna Volcano, rotten rock held in place by volcano-warmed ice sometimes loses its grip. Several times over the years, rock-and-ice avalanches have blasted down Iliamna at 150 miles per hour. Left behind on the mountain’s face is a dirty, five-mile scar, in the same place as the last one. […]
The Alsek, a world-class rafting river that flows into the Gulf of Alaska from its headwaters in Canada, may soon abandon the lower part of its drainage for a steeper one 15 miles away. The Alsek River starts in the Yukon Territory, flows through British Columbia and then on to Dry Bay in Alaska. It […]
While out on a springtime snow trail, I recently saw a dozen white-winged crossbills pecking at snow on the side of the trail. When I reached the spot, I saw a yellow stain from where a team of dogs had paused. Last spring, I saw a bunch of crossbills gathered near an outhouse. They were […]
In mid-March, it is snowing once again in Fairbanks, as it has snowed on many days since October. That makes it a good day to pick up Matthew Sturm’s new book, “Field Guide to Snow.” Sturm is a snow scientist at University of Alaska Fairbanks’ Geophysical Institute who has studied Alaska’s most common ground cover […]
