Yellowstone National Park as a Macroscopic Analogy for Space‑Phase (SP3) Behavior: Corridor Installation, Saturation, and Release

This paper presents Yellowstone National Park’s hydrothermal systems as a macroscopicnatural analogy for the behavior of the space‑phase substrate proposed in the SP3framework. Yellowstone contains over 10,000 hydrothermal features driven by heat from adeep magmatic system, including geysers, hot springs, mudpots, and fumaroles. TheYellowstone system demonstrates three core principles central to SP3: (1) substratesaturation and release, (2) installation of transport corridors (plumbing pathways), and (3)episodic versus continuous release governed by structural constraints. The Yellowstoneanalogy provides a concrete visualization of how invisible underlying substrateconditioning can guide visible manifestations, analogous to SP3 corridor‑guided matter andradiation transport.
