Farming terraces/maze/other?
The farming terrace theory seems distinctly unlikely, since (as far as I'm aware) nobody builds north-facing strip-lynchets. Also, if my understanding is correct, population levels were never high enough in Glastonbury to require terracing the tor for food production.
I'm open to the maze theory, but not 100% convinced. It doesn't help that the debate seems to have polarised between the archaeologists and new-agers, with the former group (ironically) religiously avoiding the maze theory, because they associate it so strongly with the latter group. Confusing!
Opinions?
