Briefs from the Upper Peninsula
SAULT STE. MARIE, Mich. - Tree pollen in the eastern Upper Peninsula has been especially heavy this spring, leaving thin layers of yellow dust on cars, driveways and sidewalks.
Pat Hallfrisch, a forester with the Michigan Department of Natural Resources, said spruce and pine trees are mostly responsible for depositing the powder.
"Some years it's more noticeable than others," he told The Evening News for a story published Friday.
Hallfrisch said he isn't certain why the pollen is so noticeable this year, although weather conditions can have an effect.
"It was dry for a long time, then we got rain and windy weather to bring it down," he said.
While the excessive amount of pollen is essentially harmless to most people, Hallfrisch said allergy sufferers may experience more intense symptoms.
The fishing enthusiast said he has seen oily looking accumulations of pollen floating atop Lake Superior more than 20 miles offshore.
