Survey lines on Cydonian anomalies.
    This shows how different anomalies in the Cydonia area have their structures falling on lines drawn between various features.
    This is a pyramid shape from the second MGS photo. The black dots are the tops of hills or small hills, perhaps used as survey marks in the construction of this object. The red dots are all right angles, and the numbers refer to angles. Compare this to the original unmarked photo to see if you agree with the marks
selected.
