Decades of tourist garbage thrown into the Yellowstone Geyser coughed during the eruption

A geyser in Yellowstone National Park that has been dormant for nearly 60 years has recently revealed some interesting discoveries.

A number of coins, aluminum cans, a plastic cup, and cigarette butts were among the items taken from Ear Spring Geyser when it erupted on September 15th.

Officials also found a block of cement.

But the most surprising of all? The lollipop of a baby from the 1930s.

Officials posted a photo of surprising finds on the park's Facebook page.

Some articles are "clearly historical", according to Facebook post. "They will be inventoried by the conservatives and may end up in the Yellowstone archives."

But officials warn that foreign objects can damage hot springs and geysers.

"The next time Ear Spring will burst, we hope it is nothing but natural rocks and water," park officials wrote in a Facebook message. "You can help by never throwing anything into the thermal properties of Yellowstone."

The eruption was only the fourth of the last 60 years, according to the Associated Press. The geyser spewed steam and water up to 30 feet. The geyser broke for the last time in 2004.

Ear Spring is named for its resemblance to the form of a human ear, according to the AP. It is one of the many geysers, pools and hot springs of the National Park.
