Under Baltic waters lies a 975-metre stone wall with a boulder weighing about 11 tonnes. Researchers suggest it may have funnelled reindeer toward the former shoreline, but the stones were never directly dated; nearby reindeer remains support an estimate of about 8,500 years ago. Stone lanes are also documented beneath Lake Huron, while one published count lists more than 6,700 desert kites across 11 countries. No common building tradition is established. 🦌
Possible Baltic reindeer wall, Lake Huron lanes and desert kites

Key facts
- The submerged Baltic “Blinkerwall” runs about 975 metres and includes boulders weighing up to roughly 11 metric tonnes.
- Researchers suggest it may have funnelled reindeer toward the former shoreline; they have not ruled out a natural origin.
- The wall’s stones were never directly dated. Researchers estimate about 8,500 years ago from nearby reindeer remains, rather than establishing a 13,000–10,000-year date.
- Around 9,000 years ago, lower Lake Huron levels exposed a ridge used as a caribou route, with stone lanes and sheltered waiting places.
- At Drop 45, two stone lines form a lane about 8 m wide and 30 m long; 11 stone flakes inside were interpreted as debris from making or repairing tools.
- One inventory records more than 6,700 desert kites across the Middle East and Central Asia in 11 countries; they funnel animals toward an enclosure or killing area.
- Some securely dated Jordanian desert kites date to roughly 9,000 years ago, after farming villages had developed in the western hills.
- No established connection links the Baltic wall, Lake Huron lanes and desert-kite builders.
