Another Look: Here is a different look at the Soo Locks first ship last Friday in a time-lapse video taken from the Poe Lock miter gate. In the video, the Joseph L. Block — the first ship of the 2024 navigation season — and the Indiana Harbor enter the lock and then rise to the Lake Superior water level before exiting westward. #USACE #SooLocks #GreatLakesNavigationSystem | U.S. Army Corps of Engineers, Detroit District
