Germany's drought uncovers ominous 'hunger stones'
STORY: These ominous 'hunger stones' are
being uncovered along the Rhine River
Locator: Rhine River, Germany
The boulders are usually submerged in water
but are peeking out due to the drought
There are names carved into them
next to the dates of previous droughts
some of them as far back as 1947
Their reappearance used to serve as a warning
that famine was just around the corner
