Rod and Judy visited the Soo Locks in July,
2006 and witnessed the dramatic 21-foot drop
of a cargo ship on its way to Lake Huron and
other destinations on the Great Lakes. Lake
Superior is 21 feet higher than any of the other
lakes, which means that ocean-going ships must
use the locks to reach ports in Lake Superior.
The Soo Locks are managed by the US Army Corps
of Engineers and can accommodate the 1,000-foot
freighters that move cargo and equipment between
ports on the Great Lakes and international ports.
Closed in winter, the Soo Locks
usually open in late March, making them interesting
to check out over spring break.
Here are some excellent Web
sites that explain more about this unique engineering
marvel:
