Experts have been discussing that question for years, but in recent times more and more people believe that a whole colony of giant creatures may live in the lake. In 1962 a group of people formed an organization called the Bureau for the Investigation of the Loch Ness Phenomena.

Each summer they invite volunteers who watch the lake. And in 1966, they installed cameras on the banks to prove 'Nessie's' existence. Other people made some photographs on the lake’s surface, but the pictures weren’t good enough to convince anyone, although a film made in 1961 convinced a lot of people that something exists in this lake. The film showed an object twenty-eight metres long, travelling at sixteen kilometers per hour.

People who claim they saw a monster describe it in a very similar way: it has four fins, a tail and it has a length of around eighteen meters. 

Some years ago an 18-year old girl from England had a thirty-seven kilometers journey across Loch Ness. It took her thirty hours, some of which she was swimming in the darkness and everyone applauded her for her strength and bravery.
