This year, Lake Vermilion is going to have the earliest ice-out date in history.
But, as of today, there is still some ice on the lake. The evidence is here.
Update: There’s been no announcenent (I’m not sure who actually makes the official call) but I going to say the lake is ice free as of today, April 3rd, 2012. That is a new all-time ice-out record.
Update 2.0: Apparently the official ice-out date is now April 2nd, 2012.
