In my random ventures over to RCMB, occassionally I meander into an interesting OT post. Before getting completely derailed by Global Warming arguments and political stuff, they had some interesting discussions on the great lakes freezing over that I found pretty interesting. Here's a link to a random article talking about the current ice cover:
In my spare time, I randomly take some interest in the Great Lakes water levels, which the GLWLD has a pretty cool dashboard for, but they also have some interesting stuff regarding ice cover as we approach 89% of the entire Greak Lakes being covered with ice.
Of big interest to me from this ice coverage, is the potential for introducing, reintroducing, or bringing new blood to aging populations of some animal species that can cross the ice bridges from Canada to places like Isle Royale. These potential species include wolves, moose, elk, and perhaps most relevant, wolverines. Here's a link discussing the wolves of Isle Royale and the need for new blood I found interesting.
