The US has once again said it may strike Iran's nuclear site at Pickaxe Mountain as the war heats up. President Trump has pointed out that this underground location might be a target. It's located near the Natanz area and is so deep that it’s unclear if even the strongest US bombs could destroy it. Why Is Pickaxe Mountain So Difficult?Pickaxe Mountain is difficult to target because much of the suspected facility is located deep underground beneath a large mass of rock. Satellite imagery shows extensive tunnel construction and continuing work around the site. Experts have assessed that parts of the complex could lie beyond the effective penetration range of existing conventional weapons, although the exact underground layout remains unknown.Pickaxe Mountain is located close to Iran’s Natanz nuclear complex.The facility is buried deep beneath mountainous terrain.Satellite images show continued construction and fortification.Its exact internal layout has not been independently verified.Analysts question whether existing bunker-buster weapons could reach its deepest sections.Deep Underground Nuclear FacilityPickaxe Mountain, known as Kuh-e Kolang Gaz La, is in Isfahan province, around 220 kilometers south of Tehran and close to Natanz. It's been under construction for years, with satellite images revealing tunnels and security setups, yet inspectors can’t fully access it. This uncertainty has raised concerns that it might be linked to nuclear activities. An analysis from September mentioned increased work in 2026, especially around access points, and said Israeli intelligence claimed some centrifuges had been moved there, but these claims are tough to verify. Trump Renews Strike ThreatTrump has issued new threats while discussing the ongoing conflict with Iran, focusing on Pickaxe Mountain. This makes the mountain a key target because hitting it is tougher than hitting normal nuclear sites. The challenge lies in its depth, with some areas estimated to be over 100 meters underground. Experts are skeptical that regular bombs can reach such depths. Key HighlightsTrump has renewed threats against Pickaxe Mountain.The facility sits near Iran’s Natanz nuclear complex.Satellite imagery indicates continued construction activity.Much of the suspected complex is located underground.Experts remain uncertain about the facility’s exact internal design.Its depth could limit the effectiveness of conventional bunker-buster bombs.ConclusionPickaxe Mountain has become one of the most difficult potential targets in the Iran war because of its deep underground construction and uncertain internal layout. Donald Trump’s renewed threats have increased attention on whether the US can actually destroy the facility using conventional weapons. While existing bunker-busters are among America’s most powerful tools against underground targets, experts caution that the mountain’s depth could leave parts of the complex protected. The actual level of damage that any future strike could cause remains uncertain.Disclaimer: This article is provided only for knowledge and news-information purposes and does not constitute military, legal or security advice.
