Black Dragons Caldron

Description

In 1948, Black Dragon's Caldron burst onto the landscape along a crack in the earth. It uprooted and coated nearby trees in thick mud. This feature has since shifted south 200 feet (60 m) along the crack. The spring feeding nearby Sour Lake was much more active before Black Dragon's Caldron formed. Perhaps underground changes diverted heat energy from Sour Lake to form this seething mass of mud, which a park ranger named for its color and the apparent lashing of the "dragon's tongue."
