200 million years ago, what is now the Lone Valley was covered by a tropical sea. Its coral and sponge reefs formed the light-colored rocks that are still visible today. After the Jurassic Sea receded, flowing water formed the ancient Lone River during the Cretaceous and Tertiary periods. It initially flowed into a subtropical sea near the Alps, and later at the level of today's Lone Valley, where sharks, whales, and other marine animals thrived.
A fascinating array of wildlife thrived in the valley of this primeval Lone, attracting our earliest ancestors to the Lone Valley. There they found food, shelter, and time—time they could use to develop intellectually and culturally.
Over 30,000 years ago, the people of the Lone Valley carved the now world-famous ivory figures of the Lone Valley from mammoth tusks – the oldest works of art known to mankind.
