Dragon's Mouth Spring

The photos I've posted today are all of the Mud Volcano area of Yellowstone National Park, this of Dragon's Mouth Spring one of the features near the parking area. The Mud Volcano area is on the east side of the lower loop of Yellowstone's main road and one of the worst smelling areas of the park, but very active thermally. The hot mud pots are especially noteworthy. I've only added one inset, of Mud Volcano itself, but have posted other photos of Black Dragon's Cauldron, Sour Lake, Grizzly Fumarole, of animal tracks through the mud pots and of runoff from the springs.
