World's Biggest Crater Field

Earth has been pounded from space by asteroids and comets across its history. Were it not for erosion and the oceans, Earth's surface would look much like the moon's.

It's only in the last 100 years or so that impact craters could be reliably differentiated from other types of craters (eg volcanoes), and new discoveries are still occurring.

For example this is new: "Argentina site of world's biggest crater field"

A deep-geek version of the information appears here: http://tinyurl.com/m6p3rs

It's so new it not yet plotted on Google Earth, but I found a section of it by scrolling around. Here's the Google Maps version: http://tinyurl.com/nftdzd
