Yellowstone Geyser Spews Garbage Dating Back To 1930s

Yellowstone National Park's typically quiet geyser is making some noise after spewing garbage dating back to the 1930s.  After the geyser erupted last month, employees found a Hamm's beer can, a vintage pacifier, a shoe heel and dozens of coins next to its vent.  Live Science was able to put a date on the pacifier, creating a timeline for how long the items had been resting just below the surface.  A cinder block, a broken bottle, old signs and cigarette butts were also among the contents barfed up by the geyser.  Curators are reminding visitors not to use the springs as a trash can, as they can cause damage.
