Time Team

I've been enjoying watching Time Team UK with my family on TV lately, it's my favourite show. I love the mystery of it, wondering what they are going to discover in each episode. http://www.channel4.com/programmes/time-team

A lost Civilization?

My dig team (AKA my buddies in year 2 at school) have been busy. We have been excavating a part of the site at Rouse Hill Anglican College (apologies to Mr Binnie the grounds keeper for the holes everywhere), and the picture attached shows some of our finds. There seems to be a large mixture of floor and wall tiles all from the 1970's & 80's by the look of it. Either they've been dumped as part of a land fill from somewhere else, or its part of a lost civilization, or settlement on the site before the school was built here in early 2002.
