Right you are, Mr. Nash!
I have known of the Shoal for quite some time. It is a popular fishing spot if one is brave enough to venture out there. The Wiki page does a pretty good job of explaining what it is. The ridges they detail are part of the MidContinent Rift where it makes its curve back to the south. Concerning the deepest part of the Lake; that lies out from Munising.

This is an imported and invasive thistle and is
best destroyed. Native thistle does not take over
like this one does.
