World's Only Moving Mud Puddle

So the gas that is escaping is carbon dioxide you say? Compressed carbon dioxide turns into dry ice. Dry ice would give the observable effect on the surface of the mud spring having no heat. The observable lack of heat is an illusion. Why? Here's why: when's the last time you've evacuated an air compressor by opening its relief valve? The air moving from the high pressure interior of the tank into the low-pressure atmosphere is icy cold at the point where it escapes the tank. The weight of the crust of the earth is providing the compression to the carbon dioxide like air being stored in an air compressor tank. Fissures in the surface of the Earth are providing a means of Escape for the carbon dioxide gas. The change from high pressure to low pressure occurring at the point at which the carbon dioxide Escapes into the atmosphere is making the carbon dioxide cold... the water is simply filling in a physical void left behind by the volume of escaping carbon dioxide... I'm willing to bet the energy source making the carbon dioxide gas superfluid is heat from lava thousands and thousands of feet down.
