Pressure ridges are not uncommon when Lake Manitou freezes and the ice becomes quite thick over the winter. With the arrival of Spring, the winds arise and and slightly milder temperatures begin to change the lake ice. Spring, 2008, saw high winds, which caused the pressure ridges to crack and a strong East wind,  pushed tthe ice high and deep on the western shoreline in front of our cottage. This photograph shows one example. Note the green/blue colour, which is proof that the ice was good and solid. All rights reserved.
