On Sept. 15, Yellowstone National Park's Ear Spring geyser erupted in its most violent display since 1957. For several minutes, sprays of steaming water leapt up to 30 feet(9 meters) in the air, chunks of rock and dirt spewed forth onto the ground and about 60 years of wishes were promptly reversed when the geyser gave up nearly 100 coins that hadpreviously been tossed in.

Some coins were to be expected: Who among us hasn't flipped a good-luck penny into a thermal vent? But park officials were more surprised to find that decades of man-madegarbage had also burst forth from Ear Spring - some of which dated back to the 1930s.

What have people been throwing into the geyser? Some of the historical detritus that Ear Spring coughed up includes a large chunk of cinderblock, a broken bottle, several metalwarning signs, some old aluminum cans, plastic cups, cigarette butts, someone's rubber heel insert, a vintage pacifier from the 1930s and an 8-inch-long (20 centimeters)plastic drinking straw. (Editor's note: please do not try to drink a geyser.)

Whether these foreign objects were dropped into the geyser accidentally or chucked in on purpose makes no difference. Either way, park officials wrote, it's bad for thegeyser.
