On the 5-mile snowmachine ride up to Point Barrow, we saw several fresh polar bear tracks the size of dinner plates, a pile of whalebones from last year, and a 3-foot-wide crack in the sea ice that could swallow a sled. The crack was created when an ice floe in the open water crashed into shore-fast ice.
The sounding rocket released bright puffs of tri-methyl aluminum, which scientists track from the ground to study winds near the lower boundary of space. The streak on the bottom right is formed by chemicals that have been moved and distorted by winds and turbulence.

On a clear, cold night two winters ago in Fort Yukon, Carl Andersen watched a rocket he helped design pierce the upper atmosphere. He and three other scientists shot pictures as the rocket ejected bright puffs of chemicals in an inverted V formation more than 60 miles up.
“They were the brightest things in the sky,” Andersen said from his office at the University of Alaska Fairbanks.
Twenty-five years of monitoring and studying Alaska’s volcanoes by the Alaska Volcano Observatory have improved global understanding of how volcanoes work and how to live safely with volcanic eruptions. Timely warnings from AVO throughout its 25-year history have helped reduce the impact of erupting volcanoes, protecting lives, property, and economic well-being.
The September leaves of boreal trees in Gail Priday’s backyard swirled in a mass of orange against the gray sky.
The image is now captured in Priday’s oil painting, called “Backyard,” which will be one of the many artworks featured in “Views of the Boreal Forest,” a First Friday art show.
Annie Worden and Kristen Rahilly, graduate students in Volcanology at the Geophysical Institute, provided a rich, educational experience for a group of girls aged 8 to 11.
