KEY TAKEAWAYS
1 MIN READ- A hiker discovered a 50mm mortar grenade from the Spanish Civil War at 2,351 meters.
- The location, Colladeta del Ibón de Plan, is a popular route for mountaineers in the Pyrenees.
- A specialized multi-unit operation, including aerial support, was required for a controlled detonation.
- Spanish mountain regions occasionally reveal historical explosives due to past intense military conflicts.
In a striking discovery high within the Spanish Pyrenees, a hiker recently stumbled upon a volatile explosivo artifact dating back to the Spanish Civil War. The relic, identified as a 50mm mortar grenade, was located at an altitude of approximately 2,351 meters in the Colladeta del Ibón de Plan area. This region, known for its rugged terrain and connections between mountain valleys, remains a site where remnants of historical conflicts occasionally resurface.
The discovery prompted a swift and complex coordinated response from regional safety authorities. Due to the high altitude and difficult terrain, which made ground access exceptionally challenging, a multi-unit operation was launched. This effort involved the Guardia Civil’s specialized Gedex unit, responsible for explosive ordnance disposal, supported by the Mountain Rescue and Intervention Group based in Boltaña and the regional Air Unit of Aragon.
Managing Historical Explosive Risks in Mountain Terrain
Upon arriving at the scene, the specialist team determined that the safest course of action was to neutralize the threat on-site. The explosivo was successfully destroyed through a controlled detonation, ensuring the safety of the many mountain enthusiasts who frequently traverse this popular trail. While such finds are startling, authorities emphasize that they are not entirely unprecedented in these remote high-altitude zones, which were sites of intense historical military activity.
Reflecting on the frequency of such encounters, officials noted a similar event from two years ago, where experts had to scale heights exceeding 2,000 meters to deactivate a Spanish Civil War-era hand grenade near Peña Montañesa. The historical significance of these areas, which saw prolonged partisan activity well into the 1950s, explains why these hazardous items continue to be uncovered. Security forces continue to advise hikers and mountaineers to maintain vigilance and immediately report any suspicious metallic objects they may encounter in remote wilderness areas, as the integrity of these buried munitions can degrade over time, increasing their instability and danger to the public.
