Strong winds sent a wall of ice crashing into cottages along the southwestern shore of Manitoba’s Dauphin Lake on May 10, 2013. A total of 27 houses near Ochre Beach were damaged, 13 beyond repair. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying aboard NASA’s Terra satellite captured this true-color image of the frozen lakes of Manitoba, including Dauphin Lake, on May 13.
Events like this, known as ice shoves, occur when chunks of floating ice are pushed rapidly toward the shoreline by strong winds. When the leading edge of a raft of floating ice reaches shore, large slabs of ice can surge ashore if winds provide enough momentum. Ice shoves occur frequently along lakes in sparsely-populated parts of northern Canada, but it is rare that they cause significant damage.
In this image, Dauphin Lake is the southernmost roughly oval ice-covered lake in the west. The long Lake Manitoba stretches east of Dauphin Lake. Just north of center lies the largest lake within the borders of southern Canada, Lake Winnipeg.
