Really?? Are people that stupid???

For years tourists tossed trash in a Yellowstone geyser. This stuff was just coughed up.

A surprising geyser eruption in Yellowstone National Park coughed up some surprising objects that had been tossed into it over the decades. Human stuff like coins and cans aren't surprising, necessarily, but a 1930's pacifier?

"After Ear Spring erupted on September 15, employees found a strange assortment of items strewn across the landscape around its vent! Some are clearly historic: they'll be inventoried by curators and may end up in Yellowstone's archives," park officials said on their Facebook page.

Ear Spring on Yellowstone's Geyser Hill went from being dormant on Saturday (Sept. 15) to spewing steam and water between 20 and 30 feet (6 and 9 meters) high, a height not recorded since 1957, said park spokesman Neal Herbert. It has since continued to erupt at a near-constant height of about 2 feet (0.6 meters), he said.

Ear Spring, named for its resemblance to the shape of a human ear, is one of dozens of geysers, pools and hot springs in Yellowstone's Upper Geyser Basin — among the park's top attractions that feature the popular Old Faithful. It last erupted in 2004.

Oh and you're not supposed to toss stuff into the geysers ... even though it might be fun to imagine the item coughed out 50 years from now.

The park service added on its Facebook page: "Foreign objects can damage hot springs and geysers. The next time Ear Spring erupts we hope it's nothing but natural rocks and water. You can help by never throwing anything into Yellowstone's thermal features!"
