I'm not buying the climate change argument. The lakes freezes over enough to reach the island every few years. I know this because I lived in the UP for 20 years prior to moving to MT in 2017.From what i have read on the subject is that the lake would freeze for a few months and that would allow for travel back and forth. Now they are blaming no ice bridge on global- warming[not going there]. One of the first wolves they released took advantage of temporary ice bridge and got out. I believe another was killed by pack already there. Starting to look like another failed gov't experiment.
