Pat Behling loves snowflakes. Her ardor doesn’t stop with ogling them or tasting them on her tongue. Behling tries to capture their oh-so-fleeting existence on film. It’s a hobby for Behling, 52, who works in the Center for Climate Research at the Gaylord Nelson Institute for Environmental Studies at the University of Wisconsin-Madison. To get her snowflake photos, Behling sets out microscope slides on cookie sheets. The slides are coated with a sealant, and as the snowflakes fall on the slides, they leave an impression, similar to someone making a snow angel. Behling then takes pictures through a microscope of the snowflake impression. A showing of her snowflake photos is at the Mosquito Hill Nature Center in New London until the end of January.
