The King’s Valley on Mars is proposed to contain strong evidence for artificiality. Here the different formations are considered in turn, to present a complete overview of the valley. This also provides an a priori prediction, that on reimaging these formations will appear more not less artificial. It is important to assert this ahead of time as a falsifiable hypothesis. In many cases the geology of the formations is also falsified, that natural explanations do not suffice to explain them. The sheer number of possible artifacts in 5 kilometers of this valley is also proposed to be highly unlikely to occur by chance.
