Dave climbed down the cab ladder, his teeth still rattling from the impact. He stared at the boulder in disbelief. A rock of that volume should have weighed two, maybe three tons at most—nowhere near enough to lift a 40-ton excavator.
The site manager arrived minutes later, assuming Dave had simply snagged the bucket on deep bedrock. Eager to clear the delay, he ordered the crew to bring over a heavy-duty hydraulic hammer attachment—a diamond-tipped tool designed to pulverize solid granite. The operator lined up the hammer and triggered the vibrations. The air filled with a deafening, machine-gun stutter as the hammer slammed into the dark grey stone. Crack.
The crew winced. The diamond tip of the industrial breaker had completely shattered, sending shards of metal flying across the dirt. When the dust cleared, the men crowded around the boulder. The rock didn’t have a single scratch. Instead of behaving like brittle stone, it had absorbed the impact like military-grade armor plating. Something incredibly dense was hiding just beneath the surface.
