Recent Developments at Kolang-Gaz La Mountain
High-resolution satellite imagery has revealed significant construction activity at Iran's Kolang-Gaz La Mountain, also known as Pickaxe Mountain, which houses a crucial nuclear facility. The Institute for Science & International Security (ISIS) reported that Iran has intensified efforts to fortify this facility against potential aerial attacks from the United States or Israel. This facility, which is part of Iran's broader nuclear program, has not been operational since its construction began in 2021, but its strategic importance has grown following the destruction of other nuclear sites during the Israel-Iran War in June 2025.
The satellite images from February 10, 2026, indicate that Iran is reinforcing two tunnel entrances with concrete and heavy machinery, suggesting a proactive approach to enhance the site's defenses. David Albright, president of ISIS, noted that the new Natanz site may be even harder to destroy than the previously targeted Fordow facility, which was heavily bombed in June 2025.
Broader Context of Iranian Nuclear Facilities
In addition to the developments at Pickaxe Mountain, satellite imagery has shown that all entrances to the Isfahan nuclear site have been buried under soil, reflecting Iran's heightened concerns about potential strikes. This backfilling is intended to mitigate the impact of airstrikes and complicate ground access for special forces operations. The ISIS report highlighted that these preparations mirror actions taken before the June 2025 strikes, indicating a pattern of defensive measures in anticipation of military action.
Iran's military posture has been further emphasized by the recent unveiling of ballistic missile capabilities, including the Khorramshahr 4 missile, coinciding with ongoing indirect negotiations with the United States in Oman. These discussions focus on Iran's nuclear program, with U.S. President Donald Trump threatening military action if Iran does not comply with demands to halt uranium enrichment.
Official Statements & Responses
Iran's Atomic Energy Organization head, Mohammad Eslami, indicated that Tehran might consider diluting its stockpile of 60% enriched uranium in exchange for lifting sanctions. However, Iranian Foreign Minister Abbas Araghchi has firmly stated that a complete halt to uranium enrichment is unacceptable. The Iranian government maintains that its nuclear activities are for peaceful purposes, despite ongoing international scrutiny and calls for transparency from the International Atomic Energy Agency (IAEA).
Criticism & Opposition
Critics of Iran's nuclear ambitions, including U.S. officials and regional allies, argue that the continued enrichment of uranium and the fortification of nuclear sites pose significant risks to regional stability. Experts have expressed concern that Iran's actions may indicate a shift towards weaponization, particularly given the strategic depth provided by the mountainous terrain of the new facility.
Conflicting Reports & Gaps
While satellite imagery indicates extensive construction and fortification efforts at both the Isfahan and Natanz facilities, the full extent of Iran's nuclear capabilities and intentions remains unclear. The IAEA has reported difficulties in verifying Iran's enriched uranium stock due to limited access to bombed sites, leading to concerns over the transparency of Iran's nuclear program.
What's Next
As tensions escalate, the international community will be closely monitoring the outcomes of the ongoing negotiations between Iran and the United States. The potential for military action remains a significant concern, with both sides preparing for various scenarios as diplomatic efforts continue.
