What if the ground beneath your feet isn't as solid as it seems?
Every state in America hides a hole. Some were carved by water. Some blasted by miners. Others drilled miles into the Earth's crust. Together, they reveal a hidden world of caves, sinkholes, lava tubes, mines, and boreholes that stretch far deeper than most people realize.
