Over the last month, the freighter, Calumet, unloaded just over 30 tons of road salt at the old Carbide Dock in Sault Ste Marie.
The first load was 20 tons, while the second load, just over 10 tons.
That is one sign that winter is not too far off.
Another sure sign that winter is just around the corner is when the Army Corps of Engineers lay down ice control booms on the St. Marys River at Mission Point.
Mission Point is located near the Sugar Island ferry dock.
The purpose of the ice control booms is to develop an ice field on the shoreline and prevent ice from entering the Little Rapids Channel.
They prevent large masses of ice from flowing down the St. Marys River, protecting property, the shoreline, and ice build ups in critical navigational areas.
The ice control booms have been used in this area since the 1970s to maintain a channel for navigation purposes.
The ice control booms consist of steel pontoons attached to steel wire rope that is attached to H-pile anchors.
The project started on Wednesday with the CB Nicolet getting the ice booms that were towed by the tug, Whitefish Bay and is expected to be completed on or around Dec. 1.
