Yellowstone Secrets: A big mud volcano
This impressive mud volcano, making a racket with its exploding bubbles of hot gray mud, compares well with named features in the popular spots, but almost nobody knows about it. Can you guess where it is? Clue: That's the Firehole River, and you can hear cars roaring by behind those trees.
OK, it's on the map now.
See my Yellowstone Secrets album for more little-known features in America's oldest and best national park.
