Old Faithful less faithful

The San Jose Mercury News reports that Old Faithful - the iconic geyser in Yellowstone National Park - has become less faithful because of drought conditions.

A U.S. Geological survey conducted over nine years by Shaul Hurwitz found that it now takes 1.5 hours for an eruption as opposed to just about one hour before 1959:

"Hurwitz's study examined data from five reliable geysers, including Old Faithful, from 1997 to 2006. The winter of 1997 in Yellowstone and surrounding mountains was the wettest in at least 100 years, but drought has prevailed in the area for much of this decade."
