We The People Press. What X sources say about Iran’s tunnel complex under Kuh-e Kolang Gaz La near Natanz, how deep it may be, and the bunker buster debate. Researched on X, Nov 2, 2026.
The theory
Credible X sources reviewed do not confirm weapon work at the site. CSIS and ISIS say it is likely not operational and may store centrifuge equipment. The depth concern is widely shared by analysts.
Labels: Confirmed means directly from an official or wire account; Reported means credible analysts or relayed outlet reporting; Claim-only means unverified.
What is under the mountain
| Claim | Status | X source |
|---|---|---|
| Large tunnel complex about 2 km south of the Natanz enrichment plant; perimeter fence completed, tunnel entrances reinforced and extended (CSIS imagery analysis). | Reported | View on X |
| CSIS lists at least three explanations: centrifuge assembly (Iran's 2020 stated purpose), an added enrichment facility, or relocated research activity. | Reported | View on X |
| CSIS cannot confirm or deny claims that centrifuges were moved inside; it judged the site not yet capable of enrichment work. | Reported | View on X |
| Imagery suggests a shift from excavation to internal buildout: new concrete surfacing, hardened access points, debris removal. | Reported | View on X |
| Institute for Science (ISIS): site neither operational nor in major construction; supports reporting it holds valuable equipment such as centrifuges, per Israeli intelligence cited by WSJ. | Reported | View on X |
| Western intelligence flagged it as a likely nuclear material storage site (Times of Israel, i24); Iran denies nuclear work there (AFP), as relayed by an aggregator. | Reported | View on X |
| Highly enriched uranium expected to be buried beneath the mountain. | Claim-only | View on X |
| Iran is building a nuclear device under the mountain (Blake's theory). No X source reviewed confirms this. | Claim-only | View on X |

Depth and geology
| Claim | Status | X source |
|---|---|---|
| CSIS: the site is deeply buried in granite, making it particularly difficult to destroy; even the heaviest bunker busters have limits. | Reported | View on X |
| Several tunnel entrances use a U-bend design (CSIS). | Reported | View on X |
| ISIS elevation profile: two pairs of entrances at different heights; could mean two tunnels, multiple levels, or a descending tunnel; probable ventilation shaft north of the ridge. | Reported | View on X |
| Western portals about 50 m higher than eastern (about 1494 m vs 1444 m), per a summary of the ISIS analysis. | Reported | View on X |
| Public estimates put the facility roughly 80 to 100 m underground, possibly deeper; layout unknown. | Reported | View on X |
| Open-source estimates of 80 to 145 m, granite or andesite. | Claim-only | View on X |

GBU-57 reach debate
| Claim | Status | X source |
|---|---|---|
| CNN: officials doubt the GBU-43 MOAB could destroy deeply buried sites; it is an air-blast weapon, unlike the GBU-57 penetrator. | Reported | View on X |
| ISIS: MOAB is not a bunker buster; notes options used at Fordow and Natanz in June 2025 such as hitting ventilation shafts and entrances. | Reported | View on X |
| Experts doubt the GBU-57 can reach the facility, per a roundup of public reporting. | Reported | View on X |
| CSIS stockpile analysis: low single-digit GBU-57 inventory after 14 used in June 2025; replacements take years (as summarized by an aggregator). | Reported | View on X |
| Retired Lt. Col. Anthony Aguilar says the site is beyond the reach of the heaviest US bombs. | Claim-only | View on X |
| Counterpoint: GBU-57 is specifically engineered for hardened, deeply buried targets like Pickaxe. | Claim-only | View on X |

General public facts only. Nothing here links any weapon to Pickaxe Mountain. Official declassified stockpile figures were not found in X posts during this research, so figures shown are independent estimates.
Open questions
- What is actually inside: centrifuges, components, enriched material, or nothing yet? No inspector has been inside.
- How deep are the main halls? Estimates range from about 80 m to 145 m with unknown layout.
- Is the site connected or multi-level, as the ISIS elevation data allows?
- Will Iran grant IAEA access as part of the Doha talks?
- Is there any evidence beyond claims for weapon work here, versus the undeclared sites ISIS flags (Taleghan 2, Minzadayi)?
