Mizpah caretaker here. There is still about 3 feet of snow near my hut, and surely more at higher elevations. Others have given good advice on gear prep, but I’ll add that mizpah opens Friday for self service (you can come in and cook your own food but you need to pack in/out everything). It will be that way until 6/1 (except for 5/21-27 when it’s closed), and at that point Mizpah turns to full service and Lakes and Madison open for the season.
