Willamette meteorite near locality where discovered. Side view to show protuberance 

 (above) produced during flight. The shape of a meteorite depends largely on whether or not 

 it turns over during its journey. If it does not turn over, it is likely to be chiseled by the 

 flames into a nose in front
