OBSERVATIONS
When first discovered by J.P. Skipper, this feature was presented as a possible example of artificial pipes spewing liquid. The low pixel size however will limit the possibility of that determination. What is for certain, is that the area to the north and northwest, shows several lighter variations of the dark shapes and linear striations that make up the tubular features and the 'spray'. This means their origin is one and the same (See MAA9.3). This suggests that the 'tubes or pipes' are either newer formations, or that reflections of light and shadow play is responsible for their prominent appearance in the image.
POTENTIAL FOR AN ARTIFICIAL STRUCTURE
Two tube-like formations each over 1 km in length, with one of them possibly gushing liquid.
COMMON EXPLANATION
Ground level illusions caused by reflective light and shadows.
