Geologists debate natural volcanic formation vs人工 structure. Discussion centers on whether the formation is natural or constructed One hypothesis is that it could be a volcanic dyke Comparison made to megalithic structures observed in Peru
The Natural Wall remains a mystery. One side looks like a volcanic dyke, but the block-like appearance on the other side resembles megalithic structures found in Peru. Some blocks even have rolled edges like placed stones. Locals weigh in on the debate 🗿
Note: The formation is officially called the 'Natural Wall' and is described by geologists as a resistant vertical bed of Jacobsville Sandstone, not a volcanic dyke. The volcanic dyke hypothesis is one proposed by non-expert observers to explain its appearance.
