hydrothermal area disturbs boardwalk passage in Yellowstone

A section of the Porcelain Basin Loop boardwalk in the Norris Geyser Basin was removed because the ground below sections of the boardwalk became too hot and made charcoal of the wood footings that support the structure. Luckily enough in this case, the boardwalk was shifted about 3 feet to avoid the new hot ground. Photo taken by the Yellowstone National Park geology program in 2018.
