In the depths of an Israeli cave, archaeologists found rolls of dusty manuscripts dating to the 1st century AD, and they are inscribed on a copper scroll! Scholars believe the copper scrolls represent a detailed treasure map--a list of hiding places where the priests of Jerusalem's Second Temple stored their most precious silver and gold artifacts during times of trouble. Join host Josh Bernstein in his search as he rappels into the caves outside Qumran. He then creates his own copper scroll, and uses ground-penetrating radar inside a newly excavated tunnel hundreds of yards beneath the ground.
