Two University of Iowa researchers and their University of New Hampshire colleagues have discovered
a history of the past 30 years of El Niño events recorded in Central American stalagmites. The researchers say
that their findings, published in the Oct. 18, 2002 issue of the journal Science, represent the first time that a
correlation between El Niño and stalagmites has been documented. Amy Frappier of the University of
New Hampshire is pictured above working in the Actun Tunichil Muknal cave (aka "Cave of the stone
tomb") in central Belize. (Photo by Brian Frappier.) Second photo below.
