Figure 1. — Outline map of the Henbury meteorite craters, derived from aerial photographs. The tops of the rims and 

 the outer perimeters of the floors are both indicated. Crater numbers are those assigned by .\lderman (1932), except 

 for crater IS, which was found after Alderman's study. Dotted lines indicate the area over which roclc debris from 

 the explosions can be traced on aerial photographs. Dashed lines trace the location of the rays emanating from crater .3 

 (see Rayner, 19.>9).
