A new thermal vent spewing steam in the air at Yellowstone National Park is gaining attention, mainly because it's visible from a road rather than any significant change in the park famous for its thousands of geysers, hot springs and bubbling mud pots.
When Yellowstone's roads open to car traffic in April, tourists will be able to view the new steam column from a pullout as long as the vent remains active. It's located in an area about a mile (1.6 kilometers) north of the Norris Geyser Basin.
