The timeframes must be short enough to fit biblical chronology. Creationists differ but this one sees the "ice age' starting some 4 centuries or so after the flood, by tree ring count, and lasting a few hundred years and over with a sudden melt.
Now there are issues about glacial covering of earth. i believe one creationist has suggested the "glaciers" were not ice but frozen water. that is they were not created by weight of snow but massive frozen water from rain and snow.
Yet their movement would need explanation and other details. The source of the megameltwater events, a famous topic in geomorphology here, would be explained better if the "ice" was just frozen water mostly. However I'm just suggesting this.
