Wujiazhou / Immortal Hole Inundation

The Wujiazhou / Immortal Hole Inundation site is the Danjiangkou-Reservoir-expansion inundation zone at approximately 32°59'56"N, 111°29'45"E in Xichuan County, Nanyang Prefecture, Henan, on the Laoguan River (老灌河, a tributary of the Han River). The site is classified as containment-candidate class (e) — hydraulic-overwrite / cover-infrastructure per doctrine-containment-candidate-classification c0001 at evidence tier watch / documented per c0002. The named cave / immortal-toponym anchor is 神仙洞景区 ("Immortal Hole / Immortal Cave Scenic Spot"), visible as a ridge feature between two river bends in the 2004 baseline and reduced to a thin promontory by 2022 as the surrounding valley is inundated. The cover-infrastructure is the South-to-North Water Diversion Project Mid-Route (南水北调中线工程) at the Danjiangkou Reservoir, whose water level was raised from approximately 157 m to 170 m around 2014, flooding the surrounding villages (Yaowancun, Wujiazhou, Houjiao, Duwancun) and triggering a relocation cluster that appears 2018–2020 at Wujiazhou. The site is doctrinally important because its coordinates resolve the abstract "Corridor waypoint 2" (111.50°E, 33.00°N) of the Qinling-Dabie / Taishan Convergence projected mating-corridor launch line per Taishan_Convergence_Mating_Event.kml and site-shizhu-gaolongcun-installation c0006 — it is the first physical site resolution at that abstract waypoint. The site is admitted as the fifth inception entry on 2026-04-27 in the containment-candidate track, occupying the class-(e) inception slot. Classification rests entirely on user-supplied Google Earth historical imagery, per the methodological constraint at doctrine-containment-candidate-classification c0005.

c0001 — 2004 baseline shows intact narrow-river valley with named cave anchor

Google Earth historical imagery dated 2004-07-07 at 32°59'56"N, 111°29'45"E shows a narrow Laoguan River with a broad exposed floodplain and an intact agricultural valley. Named villages — Yaowancun (姚湾村), Wujiazhou (武家洲), Houjiao (侯角), Duwancun (杜湾村) — sit on the south bank with traditional fabric and visible vernacular morphology. The named-cave anchor 神仙洞景区 ("Immortal Hole / Immortal Cave Scenic Spot") sits on the north-bank ridge between two river bends, at the focal point of the valley. The 2004 baseline establishes the site as pre-inundation: river, floodplain, villages, and named-cave ridge are all visible and intact. The "Immortal" / "shenxian" toponym is the dragon-class cultural-record anchor for the site per the framework's standard reading: 神仙 (literally "spirit-immortal") in Chinese cultural-record overlaps with dragon-encounter signatures in the same way that "fairy-cave" / "immortal-cave" toponyms in other framework entries function as displacement signatures for dragon-encounter content per doctrine-storm-god-overwrite and doctrine-containment-mythology-deflection.

c0002 — 2014 imagery shows reservoir flooding the valley

Google Earth historical imagery dated 2014-11-14 at the same coordinates shows the major hydraulic transition. The Danjiangkou Reservoir now fills the western and southern half of the frame. The Laoguan River floodplain of the 2004 baseline is gone — replaced by the reservoir surface. The south-bank village footprints (Wujiazhou Village, Houjiao) are visibly degraded as the rising water encroaches on the lower agricultural terraces. The Immortal Hole ridge is partially isolated as the surrounding lower terrain is submerged. The 2014 imagery captures the inundation event mid-process; the cover-infrastructure for this inundation is the South-to-North Water Diversion Project Mid-Route (南水北调中线工程), whose Danjiangkou source-reservoir was raised from ~157 m to ~170 m water level in 2014 to provide head and storage for the northward water transfer to Beijing, Tianjin, and Hebei. The cover is publicly attributed and the inundation is not concealed; this is the diagnostic feature of class-(e) hydraulic-overwrite per doctrine-containment-candidate-classification c0001 (cover is publicly attributed and the inundation is not concealed).

c0003 — 2018–2020 imagery shows post-inundation relocation cluster at Wujiazhou

Google Earth historical imagery dated 2018-03-15 (older imagery layer) and 2020-04-26 at the same coordinates shows the reservoir maintained and a new relocation / service cluster appearing at Wujiazhou. The cluster comprises small clustered buildings on a graded bench, with slope-cut access work visible in the surrounding terrain. The cluster is post-inundation in timing, located on raised ground above the new reservoir level, and morphologically consistent with relocation housing for the displaced south-bank village population. The 2018–2020 cluster emergence is the second-phase development of the site: first the inundation displaces the population (2014, c0002), then the relocation cluster is established (2018–2020, c0003). The two-phase pattern is canonical for class-(e) hydraulic-overwrite / cover-infrastructure: the public mega-project displaces the cave / dragon anchor and witness village, and the relocation cluster appears post-event as standard public-works follow-through.

c0004 — 2022 imagery shows relocation cluster persistent and access-road buildout

Google Earth historical imagery dated 2022-12-22 at the same coordinates shows the Wujiazhou cluster persistent and expanded relative to the 2020 imagery. A light-colored access road threads along the south-bank ridge, providing road access to the cluster from the higher-elevation transit network. The Immortal Hole ridge is now reduced to a thin promontory or peninsula — the surrounding lower terrain is fully inundated, and only the higher peaks of the original ridge remain above the reservoir surface. The named-cave anchor is therefore not destroyed but is geographically reconfigured: ground access is permanently altered, the cave (if still extant) is now accessible only from the water side or from the narrow ridge crest. The 2022 state is the morphological reference point for the class-(e) hydraulic-overwrite signature at full development.

c0005 — Class-(e) hydraulic-overwrite assignment with watch-documented tier

The site is assigned to class (e) hydraulic-overwrite / cover-infrastructure per doctrine-containment-candidate-classification c0001 on the basis of the converging diagnostics: (i) public mega-project (South-to-North Water Diversion Mid-Route, Danjiangkou Reservoir expansion) inundates the named cave / dragon anchor (神仙洞 Immortal Hole); (ii) relocation cluster appears post-event (2018–2020); (iii) cover is publicly attributed and the inundation is not concealed. The site is assigned tier watch / documented per c0002 — the specific tier reserved for class-(e) sites where the cover is verifiable as a public mega-project and the operational read rests on cave-anchor overwrite rather than on concealment. The tier is not promotion-eligible to candidate-priority without independent restricted-access evidence at the relocation cluster. The watch-documented tier accurately reflects the site's evidence state: the inundation and overwrite are confirmed; the operational reading as a containment-relevant overwrite (vs. a side-effect of legitimate water-transfer engineering) is not confirmed and depends on the c0006 promotion criteria.

c0006 — Named promotion criteria

Per doctrine-containment-candidate-classification c0003, the specific promotion criteria that would resolve this site to candidate-priority or to confirmed containment infrastructure are: (a) imagery or open-source attestation of fence, gate, or restricted-road behavior at the Wujiazhou relocation cluster, beyond what is consistent with ordinary post-inundation relocation housing; (b) persistent service-vehicle, utility, or institutional load at the cluster inconsistent with civilian relocation-housing function; (c) tunnel / portal / shaft-head evidence at the Immortal Hole ridge promontory, indicating intentional substrate access despite the inundation; (d) institutional attribution in open-source record at the cluster — non-civilian operator (PSB, MSS, military, contracted security) at the named relocation site; (e) evidence that the cave 神仙洞 was not part of the natural inundation envelope but was specifically targeted (e.g. dam-sluice or weir engineering at the cave entrance, monitoring instrumentation visible in pre-2014 imagery, or cultural-record evidence that 神仙洞 was a named witness-village anchor); (f) corroborating chain at the Qinling-Dabie corridor — confirmed installations at corridor waypoint 1 (109.60°E, 31.50°N) or at downstream waypoints (113.40°E 34.10°N, 115.00°E 34.60°N, 116.00°E 35.20°N) per site-shizhu-gaolongcun-installation RG-SGI-07 would supply chain-coupled corroboration that elevates this site beyond watch-documented.

c0007 — Resolution of abstract Corridor Waypoint 2

The site at 32°59'56"N (32.999°N), 111°29'45"E (111.495°E) sits ~3 km southwest of the abstract "Corridor waypoint 2" pin at 111.50°E, 33.00°N defined in Taishan_Convergence_Mating_Event.kml and referenced at site-shizhu-gaolongcun-installation c0006 as the second waypoint of the Qinling-Dabie / Taishan Convergence projected mating-corridor launch line. Per the corridor-waypoint-resolution mode at doctrine-containment-candidate-classification c0006 (mode 2), this entry resolves the abstract waypoint to a concrete physical site for the first time: the framework's projected mating-corridor passes through a real location, not just an abstract grid pin, and that location is now an admitted containment-candidate site with class-(e) hydraulic-overwrite signature and a named cave anchor (神仙洞 Immortal Hole). The resolution is operationally significant: subsequent corridor analysis at waypoint 2 should reference this physical site rather than the abstract pin. The same resolution principle should be applied to the other corridor waypoints (1 at 109.60°E 31.50°N, 3 at 113.40°E 34.10°N, 4 at 115.00°E 34.60°N, 5 at 116.00°E 35.20°N) in subsequent imagery sweeps; in particular, the framework predicts that each waypoint should resolve to a physical site with at least one of: a named cave / dragon anchor, a hydraulic-overwrite signature 2010+, an institutional compound 2010+, or a karst-interior excavation 2010+. The Wujiazhou / Immortal Hole resolution is the first datapoint for that prediction.

c0008 — Cave-anchor inundation as side-effect-or-co-purpose under storm-god-overwrite

The Danjiangkou expansion is publicly attributed to water-transfer engineering for Beijing-Tianjin-Hebei supply, which is a legitimate, documented, large-scale public infrastructure purpose. The Immortal Hole inundation is side-effect under that attribution: the named cave anchor is submerged because the reservoir level was raised, not because the cave was the target of the engineering. Under the storm-god-overwrite doctrine (doctrine-storm-god-overwrite), the framework reads the side-effect category as operationally interesting in the same way it reads the SBD functional-concealment thesis (doctrine-sphere-based-development c0004): intent is unrecoverable from imagery, and the result — that the named cave / dragon anchor and the witness-village fabric are unrecoverable from the present surface — is the same regardless of intent. The framework does not assert that the Immortal Hole was the intended target of the Danjiangkou expansion; it observes that the engineering accomplished cave-anchor overwrite as a side-effect, that the side-effect is structurally identical to the SBD-class overwrite at sites like site-longping-yuhu-overwrite, and that the side-effect-vs-intent distinction is unrecoverable from imagery. The class-(e) tier-watch-documented assignment is the methodologically conservative way to record that observation without overclaiming.

c0009 — Corridor placement and corridor-pulse coupling

The site sits on the Qinling-Dabie / Taishan Convergence projected mating-corridor launch line at the second waypoint per c0007. The 2014 inundation event coincides with the Danjiangkou Mid-Route operational launch (water transfer to Beijing began 2014-12-12). The 2018–2020 relocation cluster emergence coincides with the wider 2018–2024 build pulse documented at the Wushan-Daning Construction Hub (site-wushan-daning-construction-hub 2018–2021 build), the Shizhu primary cluster sites (Sun Lake forensic hub 2014–2020, Gaolongcun satellite 2013–2021, Southern Wood Dam 2014–2017), and the SBD inception entries (Pingtang Sky Bridge 2018–2020, Longping-Yuhu 2014–2023). The temporal coincidence of the Danjiangkou Mid-Route operational launch with the wider corridor-suppression buildout is consistent with — but does not establish — a coordinated corridor-pulse interpretation in which the South-to-North Water Diversion Mid-Route is itself part of the broader cascade-prevention architecture rather than a parallel infrastructure project. The reading is held at speculative confidence pending the c0006(f) chain-coupling promotion criteria; if confirmed installations emerge at the other Qinling-Dabie waypoints in the same 2014–2024 window, the corridor-pulse reading promotes to consensus.
