The garage not far from us is excavating a huge hole (for more petrol tanks, presumably). The stratigraphy was great - Son 1 and I spotted the 50cm of soil followed by 50cm of river-pebbles which are the bane of his daddy's gardening life! When Son 2 got there, his eye was caught by something different - he ended up bringing home samples of soil which had rolled outside the safety-fence, and soaking them to find out the clay-content of each one.
Wombats?? Who Knew?!
