It's super unpredictable in Minnesota, most places close down early because of staffing, I was skiing giants ridge closing day (April 6th) in an 8" snow storm with a solid 80" base left last year. The year before it was 76 on st patty's day and they had to close that day. I know lutsen stays open as late as possible regardless of staffing, same with troll. I really hope we get some April storms like last year, that was amazing. Last year I was still skiing on snow in Northern Minnesota into May! After suffering through this arctic winter, we deserve a long spring season of 35° every day and fresh snow every night.
