About Stefánshellir, Hallmundarhraun
Venture into Stefánshellir, one of Hallmundarhraun's grand lava tubes, where smooth volcanic floors lead deep into the Earth. Its complex network of passages, illuminated by a single headlamp as seen in the image, reveals the raw, textured beauty of solidified lava flows. This extensive cave offers an accessible yet intricate journey through Iceland's fiery geological past.
History & Background
Stefánshellir's history as a known site begins in 1917 when it was discovered by Stefán bóndi, a local farmer from Kalmarstungur, who lends his name to this impressive lava tube. Its existence reveals a deeper narrative of the Hallmundarhraun lava field, one of Iceland's largest, formed by a massive eruption from the Langjökull area around 900 AD. The cave itself is a product of this fiery past, a conduit through which molten rock once flowed, leaving behind its distinctive subterranean architecture. Geologically, Stefánshellir is significant for its position, acting as a crucial link within a larger network of caves that includes the famous Surtshellir and Hulduhellir. While its main entrance is over 300 meters from Surtshellir's northernmost opening, the caves are separated by only 30 meters, suggesting a close, perhaps even interconnected, system of lava tubes. This proximity makes Stefánshellir an important part of understanding the extensive underground formations of the region. Upon its discovery, Stefánshellir was noted for its rich collection of delicate lava formations, including beautiful dripstones and lava straws. Sadly, over the years, nearly all these fragile geological wonders have been broken and removed by visitors. This unfortunate loss underscores the need for respectful exploration and preservation efforts for Iceland's natural heritage, yet the sheer scale and intricate structure of Stefánshellir continue to draw adventurers seeking to witness the raw power of volcanic creation.
