(Left) Fluid was observed shooting straight up a few centimeters from small holes (about one centimeter across) on top of the low relief mounds. The denser liquid component of the fluid effluent flowed downhill, while fine sediment entrained in the emission billowed into the water column. (Right) In some places, the fluid flows from the top of the low relief mounds have built sediment features a few centimeters high around the holes.
