The pools steam and bubble, reminding you that this volcano is well overdue an eruption, taken in May 2016, in Yellowstone National Park, Wyoming, United States. The extraterrestrial-looking mineral-rich pools are caused by bacteria and thermophiles growing around the edges, creating the striking colours. The heat from three super eruptions thousands of years ago still powers the parks geysers, hot springs, fumaroles and mud pots, indicating how frighteningly active this volcano is directly under visitors feet.
