Photos are taken from the observation deck at the Soo Locks at the St. Mary’s River.
This is the major water transportation between Lakes Superior, Huron and Michigan.
The locks pass 10,000 ships per year, including the ‘Footers’ (1000 foot cargo ships).
A U.S. Coast Guard Ice Breaker opens the shipping lanes every year at the end of March.
Here is our 70 ft. tour boat in one of the Soo Locks.
Notice the water level starting to recede.
One million gallons per minute is leaving the lock.
It takes 12 minutes for the lock to get to the lake water level (up or down).
It is 21 feet of water vertical change (up or down) to get to lake level.
And the tour boat is on its way.
The shore you see is the Canadian side.
