For pollen. From the article:

“Allergy doctor Jeff Demain said Monday’s count shattered the old world record that was set in Sweden several years ago.

“A level of 175 is considered high,” Demain said. “Fairbanks had a birch pollen level of over 4000.””

It’s not just birch, either. Over the course of two days I saw clouds of pollen coming off the white spruce with every puff of a breeze. The deck was yellow with it. We finally got some rain overnight, so things are looking more normal today.

Record levels of tree pollen dust the truck.
