The deeper we went, the quieter the outside world became.
Soon, the sounds of seagulls and crashing waves disappeared entirely.
Only silence remained.
About two hundred feet inside, the tunnel opened into a large chamber.
Our lights revealed towering rock formations, pools of seawater, and walls covered with strange mineral deposits that sparkled in the darkness.
For several minutes, we simply stood there in awe.
The cave was breathtaking.
But then we noticed something that immediately felt wrong.
The First Strange Sign
Near one wall lay a pile of stones.
At first glance, it appeared natural.
Then one of my friends pointed out that the rocks had been carefully arranged.
The formation was unmistakably artificial.
Someone had stacked them deliberately.
The pile stood nearly four feet tall and resembled a crude marker or monument.
Nobody spoke for a moment.
The cave was difficult to access, requiring precise timing with the tides. The idea that someone had carried stones into this remote chamber and arranged them so carefully felt strange.
