Pressure crack poses danger, police warn

Snowmobilers are being warned by Southern Georgian Bay OPP about a large pressure crack in Midland Bay.

The detachment’s snowmobile patrol unit ventured out onto the ice on Thursday. Officers have confirmed the crack runs northeast from the Midland water filtration plant for a distance of 6.5 kilometres to Quarry Island.

The crack in this area measures close to a metre in height. Police note the overall height could fluctuate significantly if the wind shifts out of the south as expected.

The crack also branches northwest from a point midway between Snake and Present islands toward the southern tip of Beausoleil Island.

The OPP is warning snowmobilers in this area to exercise extreme caution. With milder weather making a return, ice conditions will continue to change, and may even deteriorate rapidly.
