Peering down a dizzying 100-plus feet into the man-made abyss.

Darr Beiser, Natalie diBlasio and I descended 100 feet below the ground in southeast Washington recently, then traveled over a mile on rail to reach the tunnel-digging phenomenon "Ladybird." The 440-foot long, alien-like machine is worming a 26-foot diameter hole beneath the Potomac River that will handle storm overflow to aid in cleaning future generations of D.C.'s rivers.
