Five people are safe after the sport utility vehicle they were riding in went off the road and into an inactive hot, acidic geyser in Yellowstone National Parkofficials said Friday.
The passengers, whose names were not released by officials, were driving Thursday morning near a Sesquicentennial Geyser Thermal Pool when it went off the road.
The five people were able to get out of the acidic 105-degree Fahrenheit (41 degrees Celsius) water on their own after the crash, park spokeswoman Morgan Warthin said in a statement.
The passengers were taken to an area hospital for treatment of non-life threatening injuries.
The road was closed for about two hours Friday while the SUV was extracted from 9 feet of water, Warthin said.
Semi-Centennial Geyser has been inactive since a major eruption in 1922. It is located near Roaring Mountain between Mammoth Hot Springs and Norris Junction.
Visitors can visit five types of hydrothermal features in the park and there are more than 10,000 such features at Yellowstone.
Park officials said the incident remains under investigation.
