Been done.
Meteorites are found in the Arctic, Antarctic, Greenland and places with large glaciers. One reason is they are visible on the surface, but another reason is they are collected by the glacier, carried along, and concentrated in certain places where the ice evaporates at the edge of ridges.
Impact craters have been found, some recently through satellite photos. Because of erosion, many craters are hard to recognize.
But as far as finding craters by flying over snow, I don't think you'd be very successful. Large meteorites that make craters are few and far between, thank goodness. Most meteorites do not leave such markers long enough to be a useful means of finding them. Unless the crater is a hole in your roof or car or something anyway. :wink:
