Three young people in Portugal took a surprising picture of a “hole in earth” while traveling to the National Reserve of the Estrela Mountains not long ago! From a distance, I thought it was another work of aliens.
In fact, the hole in the lake is a dam. The tunnel is more than 1,000 meters deep, and water from the surrounding lake flows in.
A “hole in the earth” unexpectedly appeared on a lake in the Serra Estrela Natural Park in Portugal. There was a huge gap in the lake, and the lake water continued to pour in.
This is not a harbinger of the end of the world, nor is it the work of aliens, but a local dam built more than half a century ago. The unique scenery is amazing.
