Five people were taken to a hospital for treatment after their SUV crashed into a hot, acidic thermal feature at Yellowstone National Park last week.

The vehicle became fully submerged in 9 feet of water inside the inactive Semi-Centennial Geyser thermal feature after it inadvertently drove off a road around 10:40 a.m., park officials said in a news release.

All five occupants were able to escape on their own and were transported to a nearby hospital with non-life-threatening injuries. The road was closed for about two hours on Friday to remove the vehicle.
