An interesting object more likely to be vesicular rock than something artificial, but which could warrant closer examination. The objects and the darker soil next to them may actually extend further, if the undulating surface is dipping as it seems it may be doing, though hard to tell in this image.
POTENTIAL FOR AN ARTIFICIAL STRUCTURE
Three sloping edges inclined at a similar degree, suggest an eroded, pyramidal structure. Its small size make it comparable to some prehistoric rock cairns found in the British Isles and elsewhere on the Earth (MAA-020.4). A mound of material of similar hue and texture to the object's left, may be the eroded remains of a second structure.
A piece of volcanic rock; vesicular coria or basalt (MAA-020.3), with an accumulation of soil built up within a cavity.
