it helps to see it in person to know, at least intuitively. who knows if the is a SMALL rise in the land underneath, but silsbury hill is distinct and visible from miles away.,, is circular and conical and there is nothing remotely comparable to it in height or shape in that area that I have ever seen.
Wow. Thanks for that reply, because I knew it had to be actually something that triggered all the attention, something that set it apart.
Really, I have always found Sillbury Hill to be interesting, kinda nice to know that bit.
