ONAMIA — Walls of wind-swept ice are grinding into houses and threatening a resort on Lake Mille Lacs.

The Minnesota Department of Transportation says the mini icebergs also are causing problems on lakefront roads and are intermittently blocking lanes of Highway 169 south of Garrison.

Ice has swept onto the golf course of Izatys Resort in Onamia.

Ice damaged Randy Dykhoff’s property along the shore north of Garrison over the weekend. Dykhoff, of Mound, was notified by the sheriff’s office of the damage.

He says he carried several wheelbarrow loads of ice from his kitchen.
