You are buying a game. The game is disguised as a particular sort of regionally produced archaeology journal which the author saw for sale in state parks when they were young.

In this solo game you are creating the results of an excavation of a cave mouth which has been a frequently used campsite for a thousand or more years. You do this backwards, building up history from the bedrock up.

You will roll a die and add dirt, building the cave floor upwards over time. At some points there will be archaeological finds 'uncovered'; you will operate a flowchart to learn about that find and how it came to be there.
