According to Minneapolis Assistant Fire Chief Kathleen Mullen, a man called 911 around 7 a.m. Monday and said he was lying in the snow by a riverbank, unable to move, the television station reported.
Mullen said the man had landed on an ice shelf on the banks of the river.
A rescue crew and medical personnel were lowered from the cliff to the victim and were able to put the man on a board so he could be lifted to safety, KARE reported.
Mullen estimated the man had been on the bank for at least three hours after falling, the television station reported.
"Pretty obviously he had been down there for hours, so he was very cold, unable to help us with standing or manipulating any kind of equipment," Dean Anderson, who was part of the rescue team, told KARE.
The man has not been identified yet, the television station reported.
