When Pete G first brought the mound to our attention earlier in the year there were several names put forward as to what it should be called; among them was 'The Silbury Mound'.
I've never liked the name 'Silbaby' A) because it's hard enough to get the authorties to do anything as it is without giving them extra ammunition in the form of a 'silly' name (no pun intended) and B) the name 'Silbaby' suggests that the mound is later than Silbury - we do not know that. TGB may be older than Silbury itself.
