Not everything that makes an arc on a map or air photo is an impact crater. Click the link to see some examples of places that are repeatedly put forth as possible impact sites despite a complete lack of impact evidence.

If you didn't know better, you'd suspect meteors were targeting Australia, North America and Europe. It's not that there are so many craters there, it's that there are so many geologists there, plus countries affluent enough to do detailed geologic mapping. A complete map would have the whole earth covered to the same density. To show you how hard it can be, the Chesapeake Bay impact structure, on the doorstep of Washington D.C., was not discovered until the 1990's, because it is completely buried.

Then there are the oceans. Only a handful of marine impacts have been identified. Impacts capable of making 5-10 km craters on land will merely dig a hole in the ocean and stir up the bottom sediment. Bigger impacts might crater the ocean floor, but water rushing back into the crater will carry debris and fill in the hole. Plus, our knowledge of the ocean floors is still pretty sketchy.

Impacts in ice caps will soon be erased as ice flows into the crater. Impacts big enough to penetrate the ice sheet will make a crater, but ice will soon flow in and cover it. Were there impacts on the Pleistocene ice caps of North America, Europe, and Siberia? Probably. Have any been identified? Not yet.
