Flight disruptions continue Friday in Alaska as volcanic ash drifts from Russia
A long, thin cloud of ash began drifting toward the Aleutian Islands on Wednesday and continued east toward the Gulf of Alaska, where it caused major disturbances for air traffic starting Thursday. Volcanic ash is a danger to planes because it is abrasive and can cause engines to fail. Alaska Airlines canceled 51 flights that day, the company said in a statement. Alaska Airlines canceled 11 flights by 6 a.m. and said more are possible, with delays likely through the day.

Winter Travel, Access and Changing Snow and Ice Conditions
The Copper River Basin in Alaska has experienced less reliable snow and ice conditions in recent years, impacting winter activities such as trapping, hunting, and gathering firewood. This study, based on nine oral interviews with local residents, reveals that crossing rivers has become more treacherous and difficult, with significant changes in ice conditions observed since the 1970s. Decreased snowpacks and increased shrub growth have also posed obstacles for accessing winter trails, requiring individuals to cut through forests. These changes, combined with socio-economic and technological factors, have affected the way people engage in winter activities in the Copper River Basin. Overall, this research contributes to the understanding of climate change's impact on winter activities in Alaska and the Circumpolar North.
