The Legend Of The Cerberus Volcano



Have you ever tried to type a number on a calculator that is just to long?This is how long The Cerberus Volcano dates back to.The carbon-testing machine actually had the infinite number on it after it was tested.The locals of Greece say it has been there even before their great-great grandparents.They know this from a legend passed down for many generations.This is the legend according to the residents of Greece.
In Greek mythology Cerberus was a three-headed dog that guarded the gates to the underworld.One night a slow,silent stream of lava flowed down into the Mediterranean sea.It evaporated the water due to it’s intense amount of heat.Next it flowed straight into the hole where the Medditeranean sea used to be,overflowed and kept advancing. Finally it reached a large village which was the capital of Greece.The lava was so hot that it burned the city down without touching a brick.Suddenly molten rock filled the top of the volcano to stop the flow of the lava.
Nobody had heard of the deaths until the next Olympics,when people arrived in Greece to find it in ruins.Many scientists rushed to the scene to investigate what had happened.They noticed hot lava puddles and said a volcano had erupted and that lava had burned the city.Next someone shouted they wanted revenge on the volcano, and so did a few others.Next everyone wanted to destroy the volcano.So onward to Mount Cookie Rainbow they marched (The Cerberus Volcano at the time).
People brought bug spray,plastic bags,and soda cans to pollute the volcano.This was their idea to destroy it.People threw all the trash they could on it.Someone even threw his sewage system on it!This went on for 7 hours. It started at 7:30am and ended at 2:30.Finally at the last hour the volcano started to rumble.Finally Cerberus the three headed dog erupted from the volcano.This is why it’s called The Cerberus Volcano!
Everyone dropped their things and ran.The boarded Noah’s Ark Tourist Tour Boat and sailed to what is now North America. As they crossed the Mid-Atlantic Ridge Cerberus fell!It had appeared Cerberus had fallen into the Mid-Atlantic Ridge!While everyone was cheering they stopped rowing the boat.This gave enough time for Cerberus to grab them and bring them down with him. If he wouldn’t have done this North America would have been discovered earlier, and 1,000 people wouldn’t have died.
