DISINTEGRATION OF A COLOSSUS. The cauli- 

 flower in this stage is rapidly approaching the ap- 

 pearance of a mere cabbage. The height of the 

 base-surge is easily estimated by comparison with 

 the "Salt Lake City" just at the edge of it. Near 

 the "Salt Lake City" clumps of spray and white 

 marks in the water are splashes made, presumably, 

 by portions of the LSM-60 falling back into the 

 Lagoon after a spectacular flight into the air. Un- 

 like Test Able, the Baker bomb was not a "self- 



cleansing" shot. Radioactivity in the Lagoon per- 

 sisted for weeks. It produced in the salt water 

 lines and condensers of various returning Cross- 

 roads vessels a radioactive residue which was dis- 

 closed by a precautionary check made when the 

 ships arrived at the West Coast. During the entire 

 conduct of Operation Crossroads no casualties 

 from radioactivity occurred, testifying to the ex- 

 treme precautions taken. OPPOSITE. Second 

 base-surge forms inside first.
