The City of Evanston reminds visitors to the lakefront to walk only on the sandy beach section and not on the ice.

The City of Evanston’s lakefront now has significant areas of shelf ice on Lee Street Beach and South Boulevard Beach, with some sections of shelf ice at other public beaches.

Shelf ice is formed by waves pushing ice against the beach. It is very dangerous to walk on, because the ice is attached not to the bottom of the lake but only to the shore.

The ice may appear stable, but it is floating on water. Cracks, thin ice or holes may be hidden by drifted snow. Anyone who ventures onto shelf ice could easily fall through, and rescue is nearly impossible.

Those who plan to view Evanston’s beautiful lakefront scenery should be sure to stay on the shore and never walk on snowy or icy areas or mounds of snow near the lakefront.
