On the other side of the marsh is a tree-covered rhyolite lava flow, and at the base of the flow is a new thermal feature marked by a plume of steam and that formed in early August 2024.

Among the vast forests, herds of bison, and steaming geysers, a new hydrothermal feature has emerged at Yellowstone National Park.
After an exciting summer, with the park seeing a hydrothermal explosion at Biscuit Basin and Norris Geyser Basin, one of the park’s scientists also spotted the new hydrothermal feature. According to a news release from the U.S. Geological Survey (USGS), the new feature “popped up right in front of our eyes — literally!”
The new feature could be seen from the road, and although it seems to have gone nearly dormant over the winter, researchers at the park think it may come back this summer.
Looking southeast at the hydrothermal feature that formed in August 2024 just north of Nymph Lake. Steam is emanating from a vent that is partially full of water to create the frying pan feature nestled in the newly formed vent. A thin grey layer of silica mud covers the vent area.
