The Mountain That Wasn’t Touched: Satellite Images Reveal Mysterious Activity at Iran’s Deepest Nuclear Site
New satellite imagery from the Institute for Science and International Security (ISIS) shows suspicious movements at Iran’s underground nuclear facility beneath "Pickaxe Mountain." While other Iranian sites have faced precision strikes, this fortress remains untouched and now, Tehran appears to be sealing it off.

According to a report by Channel 12 based on the new imagery, a significant physical change occurred at the site on April 22. Large mounds of earth were used to partially block two eastern tunnel entrances.
Key findings from the imagery:
A Pattern of Fortification
This "earth-moving" maneuver follows a series of suspicious upgrades recorded at the site earlier this year. Authorities observed the sealing and concrete reinforcement of older tunnel shafts that have been active since 2007.
Security analysts suspect that Iran may have transferred sensitive equipment or high-value materials into the mountain and is now working to isolate and protect them within the fortified complex.
The "Impenetrable" Vault
"Pickaxe Mountain" is regarded as one of the most mysterious nodes in Iran’s nuclear network. IAEA inspectors have never been granted access to the site, which is buried at an extreme depth, reportedly deeper than the Fordow facility.
Why this site matters:
As Tehran seals the doors to its deepest secret, the West is left watching from above, wondering exactly what (or who) is being hidden inside.
