Hot springs in Yellowstone National Park have wooden walkways built around them D. to keep people from eroding the area around them.
Why the wooden walkways are built
The thermal features in Yellowstone are unique and irreplaceable. Stepping on them can damage the delicate formations and disrupt the microbial life that thrives in these environments. So, walkways guide people around these sensitive areas, minimizing their impact.
In addition, the constant flow of water and foot traffic can erode the ground around hot springs. Walkways channel people in specific directions, reducing the overall impact on the terrain.
