Planetary Signal Architecture III: Signal Preservation
Signal preservation determines whether ancient event information remains recoverable through modern geological and geophysical datasets.
The Entrance
Antarctica remains the primary preservation archive within the framework.
The Exit
The Arctic Circle remains the opposing preservation domain for comparison and verification.
The Middle Mountain
The middle mountain remains the organizing bridge connecting preserved signal across domains.
Observational Constraints
Preservation depends on scale, structural continuity, resistance to overprinting, mantle persistence, field stability, and geological memory.
Reconstruction Question
Which planetary signals survive long enough to support event reconstruction?
