Rangers at Yellowstone National Park acted quickly to intervene after a man was spotted leaving the safety of the boardwalks in the Upper Geyser Basin to peer right into Old Faithful, the park's most famous geyser.
Going off-trail in Yellowstone's geothermal areas is strictly prohibited due to the danger of visitors damaging the ecosystem, falling into pools and springs, or falling through the thin crust covering the scalding hot groundwater. Those who ignore the warning signs can face hefty fines, as actor Pierce Brosnan discovered earlier this month when he was ordered to pay $1,500 for leaving the trail at Mammoth Terraces.
