Pyramid in the Quarry

The government concealed the excavation site that had begun for drilling. Each day, workers were digging deeper into the ground, creating a quarry, although local geologists knew there were no valuable minerals there. But they couldn't hide the secret for long. With every meter they dug, an unknown structure began to appear. When the site was fully excavated, it resembled a pyramid from another civilization.
