A few miles south of the Strait of Magellan near Cape Horn a long narrow channel named "St./San Sebastian" formerly flowed from the ocean 35 miles inland where it connected with the Strait of Magellan near Porvenir, Chile. Many wrecks went down in this channel prior to it's natural closure in the early 1800's. The narrow channel combined with the bay tides acted like a chute with a ferocious tidal flow that was legendarily harsh to sailors, they often skipped San Sebastian Channel in favor of the "calmer" Strait of Magellan to the north.
The coordinates I had for a certain wreck kept showing up on land to the point where I thought I was crazy but the more I researched the more plausible it became. Here are the links that show earlier maps of how the areas waterways changed dramatically and a Google earth image so you guys can see where the ocean scarred the land and flowed through... will I ever dig up a shipwreck down there, probably not lol but I thought it was interesting how dynamically our world changes sometimes.
Historical maps and evidence from past visits to the area:
In Search of San Sebastián
Todays view, you can see where it ran SW from what is now Bahia San Sebastian: https://maps.google.com/?t=h&q=http://mrdata.usgs.gov/mrds/kml.php?labno=10039038
