fast ice / lake superior
Lake Superior fast ice- -about 100 km north of Sault Ste. Marie- -Ontario Highway 17, kilometer marker 1148.
Fast ice is an extensive unbroken sheet of ice that is “fastened” to the shoreline or shoals; the ice forms from freezing temperatures (air and water), waves, drift ice, and snowfall. This fast ice varies from 3-4 meters in height
As of March 15
This site is now covered in an unbroken ice ridge, about 5-8 meters thick and extending over 50 meters from shore. Beyond this ridge, ice, of various thickness, extends almost a kilometer from shore--open water is now a kilometer away.
This sheltered bay, on eastern Lake Superior, is part part of the Mamainse Point Formation: an area of the Midcontinent Rift System characterized by Precambrian (Mesoproterozic) volcanic activity over a billion years ago.
