Organizers postponed the Bogus Creek 150 sled dog race in the Yukon-Kuskokwim Delta after forecasts called for wind chills near 40°F below zero, raising safety concerns for mushers, dogs, and trail volunteers.

Heavy snowfall in Haines, Alaska, last week has increased the risk of avalanche in the area, experts say.

The 81-foot tender F/V Pavlof sank Thursday morning while moored in Haines Harbor, prompting an oil-containment response and salvage efforts. Harbor staff, divers, and local vessels worked through low tide to free the vessel and limit contamination.

On Thursday, for the first time, the sheen was reported in Krestof Sound, an area where Pacific herring are known to spawn in the spring.

The grounding ruptured one of the tug’s fuel tanks, which can hold around 13,000 gallons of diesel fuel.

Homeowner Bart Henderson headed back to Haines from Mexico after a fuel-feed line from a heating oil tank to a furnace burst and potentially leaked. “We’ve got a pretty good idea that the cause of the leak was from the hard freeze and then the warm weather,” Pikul said. “There was some frost heaving of the ground and it compromised the feed line.”
