(YELLOWSTONE N.P.) – A group of tourists is in hot water, quite literally. A Wisconsin man contacted Yellowstone National Park officials after he saw about 30 people walking on the cone of the iconic Old Faithful geyser through the park’s webcam. Park rangers cited four people for walking off the trail in the dangerous thermal area, a charge that carries a $125 fine. The tourists claim they didn’t see the dozens of signs warning visitors to stay on the boardwalks.
