Ring of Truth, Part 4: Clues
- 1987 ----- color ----- 60 min ----- vhs
- In a handful of gravel dredged up from the bottom of the Mediterranean Sea, scientists have drawn a startling conclusion: the Mediterranean was once an arid, windy, salt desert. Philip Morrison retraces the expedition of a team of geologists searching for the secrets of the Mediterranean's past. Discerning scientific truth from small clues is a process that is carefully examined.
