No prior knowledge assumed, and that is not a polite formula
What it covers
How the local river changed course three times in six hundred years, and what that did to the villages either side of it.
What it assumes
Nothing. There are maps, photographs, and no technical vocabulary that is not explained on the slide where it appears.
Practicalities
An hour with twenty minutes of questions. Level access from the car park and a hearing loop that was tested last week.
