OBSERVATIONS
The object sits amongst conventional rocks and appears out of context with the natural geology surrounding it. However, there could be more than one object here, which would make it less anomalous.
POTENTIAL FOR AN ARTIFICIAL OBJECT
Angular, geometrically proportionate dimensions suggest artificiality.
COMMON EXPLANATION
Eroded fragment of rock. Ventifact.
