		    Following the last paper of the session will 
		    be the premier showing of the documentary video, 
		    "Secrets in Stone,"a history of the search for 
		    geomagnetic reversals and the dramatic confirmation 
		    of sea-floor spreading.  The film uses original 
		    photographs and interviews with principal 
		    scientists to convey the excitement of scientific 
		    discovery. The concepts of geomagnetic reversals, 
		    sea-floor spreading, and plate tectonics are 
		    illustrated through vivid animation and are 
		    explained in language intended for a general 
		    audience. Film maker David Donnenfield will introduce 
		    this 30-minute video, which was produced in 
		    association with the U.S. Geological Survey.
