World-renowned cave explorer Bill Steele is adding new passages to Texas maps, foot by foot
In a dark tunnel near the entrance of Honey Creek Cave, Bill Steele buckles his helmet and tugs on a pair of swim fins.
The world-renowned speleologist scoots to the edge of a ledge, then eases into a chilly underground creek. He’ll spend the next two hours swimming through this dark, watery passage beneath the Texas Hill Country.
