Once in a great while, a really big meteor smacks the earth with a vast concussion, digging an "explosion crater" like the one near Canyon Diablo, Ariz. Such craters are rare. Unless the meteor hits in an arid region, its dent is smoothed down quickly (in terms of geological time) by erosion and other natural forces...

From ground level the crater is not impressive. Its rim looks like a low, rocky ridge above a featureless plain. Apparently the few who have passed near it hardly ever gave it a second glance...
...Harvard meteor authority Fred L. Whipple, associate professor of Astronomy and Chairman of the Astronomy Department, has been awarded the Smith Prize by the National Academy of Science, the College Observatory announced Thursday...
Among Whipple's contributions are studies of the variations of temperatures according to altitude, the mapping of meteor orbits and the investigation of meteor through photography and radio echoes...
...observatories, known locally as "Whipple's Wagon Train," set out from Cambridge in August mounted on surplus government trucks and trailers. Although meteor photographing can be successful only on nights when the moon to darkened, hundreds of photographic plates have been exposed in the last five months...
