Visit to glacier begins with wildlife encounter
We heard a loud buzz. A hummingbird hovered in front of my cracker. As I held still, the hummingbird probed the peanut butter, twice, with its needle beak. The cracker transferred the vibration to my left hand, tickling my fingers. As the bird zoomed off, I looked over at Ben to confirm the experience.
“I think you have superpowers now,” he said.

The peak of summer warmth is near
By Ned Rozell You may not notice it as you scooped fish out of the Copper River or rode your bike through the tawny light of 10 p.m., but Alaska is about to make a left turn toward winter. Much of the state will soon reach the average yearly date when the air won’t get any warmer. In Fairbanks, on July 19 the average daily temperature based on about a …

The muskox’s odyssey: From Greenland to Alaska
By Ned Rozell Leaving cloven hoof prints from the Yukon-Kuskokwim Delta to the Arctic National Wildlife Refuge, more than 3,500 muskoxen live in Alaska. All of those shaggy, curly-horned beasts came from one group of muskoxen that survived a most remarkable journey in the 1930s. In 1900, no muskoxen existed in Alaska. Though the stocky, weatherproof creatures have survived in the Arctic since the last ice age, the last reports …

Low-displacement landslides explain unusual West Virginia landscape features visible in lidar imagery
Like so many older landslides in the Appalachians, the significance and cause of these features is unknown. Because they are so numerous and are only visible using lidar data acquired in 2016, they may represent an untapped resource of useful information about the recent history of Appalachian landscapes.

Bringing the world to a standstill
By Ned Rozell 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 pit. About six miles away, hot ash began spewing from the ground …
Alaska writer awarded an honorary degree
In “The Firecracker Boys,” Dan O’Neill explored “a piece of university history most people were happy to move on from.” He detailed a UAF president’s support of a 1950s Atomic Energy Commission proposal to create a harbor with nuclear detonations not far from the village of Point Hope.

Wolf-virus study shows the virtue of space
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. Scientists used blood samples taken over several decades from wolves on the Alaska Peninsula, Denali National Park and Preserve and Yukon-Charley Rivers National Park and Preserve. They also used samples from wolves living as far east as the Upper Peninsula of Michigan and as far south as Arizona.

Interesting sedimentary basin structures in fold-thrust belt outcrop patterns
By Philip S. Prince Fold-thrust belts developed in sedimentary rock sequences produce interesting and complex patterns on Earth’s surface. These patterns become even more complex and intriguing when the folded and faulted sedimentary layer sequence contains internal structures that pre-date thrust belt development. A particularly outstanding example of this effect is the Talar Syncline of the Makran fold-thrust belt, in which an extensional growth fault depocenter has been folded, uplifted, …

The secret life of an Alaska fish
By Ned Rozell 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 Wildlife Service in Fairbanks. Many years before he started that career, he …
