If you are planning on driving in Yellowstone National Park when most of its roads open in April, you could drive by one of the latest thermal steam vents in the famed hotspot. The new hydrothermal feature is about one mile north of the Norris Geyser Basin within a region called the Roadside Springs thermal area .

A park scientist noticed it about two weeks after a hydrothermal explosion along a boardwalk during the park’s overactive summer.
