Lockne crater, Impact structure in Östersund Municipality, Sweden.
Lockne crater is an impact structure in Östersund Municipality spanning approximately 7.5 kilometers across. The site displays exposed rock formations showing the deformation and transformation that occurred during the ancient collision with an asteroid.
The crater formed approximately 458 million years ago during the Late Ordovician period when an asteroid roughly 600 meters wide struck a shallow marine environment. This impact event reshaped the local geology in a way that remains visible today.
Researchers and geologists from multiple countries gather at this site to study impact processes and contribute to planetary geology knowledge.
The crater sits about 21 kilometers south of Östersund and offers direct access to geological features through established viewing points. Visitors can examine the exposed rock formations up close from these designated locations.
This crater forms part of a double crater system with nearby Målingen, created when two separate asteroid fragments struck Earth at the same time. The two neighboring structures demonstrate a rare example of multiple impacts from a single event.
