Lake Superior nearing rare ice-over
DULUTH — A frigid winter is pushing Lake Superior toward a complete ice-over for the first time since 1996, although there’s still a ways to go before you can skate from Duluth to the Soo Locks.
Lake Superior had at least some ice across an estimated 91 percent of its surface as of Thursday, according to the Great Lakes Environmental Research Laboratory.
That compares to the 40-year average annual Lake Superior ice coverage for February of just 30 percent.
