When the lake ice thunders

Quoted: John Magnuson, UW-Madison limnologist

Ted Iltis was in his Middleton home near Lake Mendota on a recent Saturday morning, sitting at his desk when he heard an explosion and felt the house shake.

There is even a name for it – “lake thunder” – said UW- Madison limnologist John Magnuson, a longtime student of Madison’s lakes, especially Lake Mendota.
