The runoff near Roaring Mountain in Yellowstone National Park is likely to be highly acidic due to the presence of numerous fumaroles. These steam vents emit sulfurous gases, including hydrogen sulfide, which can combine with water to form sulfuric acid. This acidic runoff can flow down the slopes of the mountain, creating a harsh environment where little vegetation can grow. The runoff may eventually enter nearby streams or rivers, potentially impacting the pH levels of the water and the surrounding ecosystem.
