The nearest volcano was a fair distance away.  The only way to get there in time was to sail again.  They decided that it was well worth the risk and set off on a new raft made out of one giant piece of bark.  After sailing for a little bit, they see another boat out on the water.  The uncle uses binoculars and sees that the boat has ten foot tall prehistoric people on it.  As the group makes it to the volcano they see that it had just stopped erupting. The three end up sitting on a giant rock inside it anyway.  Then the volcano erupts again shooting the rock out.  Hans grabs the nephew and uncle because the passage is getting smaller.  A large rock off to the side nearly smashes the nephew off the rock, but since Hans is already holding him, he can stay on.  When they come out of the volcano they slide down a grape farm in Italy.  The whole group makes an amazing discovery, they are not in Antarctica like there compass said they should be.
