Continues to Deepen  A massive sinkhole in western Kansas
continues to grow. The sinkhole recently developed in Wallace
County, near the town of Sharon Springs.  By the time it was
noticed by a rancher, the hole was more than 200 feet across and
90 feet deep.  The sinkhole has taken many by surprise, though
not Rex Buchanan, who heads the Kansas Geological Survey.
"Certainly, the location isn't surprising. Wallace County has
had sort of a history of producing these things, and I've been
to some of those locations, so in that sense it's not
surprising," Buchanan said. "This is a pretty good-sized one,
but the other ones out there are pretty good-sized as well. This
doesn't occur every day, but it's certainly not out of the
ordinary."  Buchanan said sinkholes like this one are created by
the dissolution of underlying rock deposits, such as chalk or
salt.  Some have suggested this sinkhole was caused by the
removal of too much water from the Ogallala Aq
