Photo by @shonephoto (Robbie Shone) - The Monte Corona (Crown Mountain) lava tube system on the Canary island of Lanzarote must rank as one of the world’s classic lava tubes. This lava tube was formed during the eruptions of Monte Corona volcano some 3,000 - 4,500 years ago. Pictured here, a team of Italian cartographers survey the lava tube using a high precision 3D laser scanner. Such a high level of accuracy means that each drip of solidified lava that can be seen in the roof of this tube will be individually scanned and projected into the final 3D map.
