This is what a typical blue ice field looks like from the ground- where the meteorite hunter wants to be. A seemingly endless expanse of nothing but clean, blue ice thrust up from deep within the East Antarctic icesheet. It really is blue, for the same reason the sky is blue, and deep clean water is blue-H₂O scatters blue light preferentially resulting in an astonishingly deep color. When we find an area like this, we're pretty sure any rock we find had to have fallen there from the sky.
