MILLE LACS, Minn. (FOX 9) - Piles of wind-swept, built-up ice are threatening Mille Lacs homes and businesses.
The strange phenomenon is not unusual for the popular Minnesota lake, however. The ice piles threaten buildings surrounding Mille Lacs each year.
What happens is the ice on the lake drifts with the wind and is swept up onto the shore. Sustained high winds created this effect on Mille Lacs Monday.
