Poor trail conditions have pushed the Kuskokwim 300 Season Opener race back another week.

Some mushers worried what the warm weather would mean for the trail ahead.

Four teams had scratched as of 7 p.m. Saturday because of the icy conditions, said Kuskokwim 300 race director Madelene Reichard. "It's the same thing for all of them," Reichard said. "The dogs aren't used to running on the ice, and people were wanting to keep their dogs healthy."

Due to consistent above average winter temperatures, there are many known and developing open holes on the river. I was on the trail working at the Bogus Creek Checkpoint. Most of the trail had no snow cover, and the majority of the race was run on glare ice over the tundra.

For the second time in three years, the Iditarod Trail Sled Dog Race will move its official start from Willow to Fairbanks due to poor trail conditions that race officials determined unsafe.
