The Volcanic Eruption of Vesuvius

We have letters from pliny the younger. And he describes, and it is our only eyewitness account,. He describes a huge set of plume, set of cloud a sort of erupting out of the mountains. It's one date i do know, a d 79. But as to the precise date, there's still quite a lot of good, hard cort discussion about that. We have their carbonized remains in pompeii which are near this site. So we get into things like the fact that they had to be later in the year.
