Somewhere very specific ..... hopefully this should keep me out of the firing line for a bit! 🙂

Deserves a clue .... of primary interest to dedicated rock-botherers!

Robcol ... not to do with climbing.
It's the K-T Boundary
Where the light rock is there were dinosaurs .... where the dark rock is, no dinosaurs ..... the thin dark line between them is the iridium and tektite rich debris layer from the asteroid strike that wiped them out ..... that layer is found all over the world but the significance of this particular place is that it is the outcrop in the Bottaccione Gorge near Gubbio in Italy where Alvarez and Alvarez (father/son, physicist/geologist) first identified it .... their work turned the 'asteroid extinction event" from one of many unsupported possible theories for the dinosaur's disappearance into the accepted theory it is now.
Revolutionary piece of geological theory and it happened right there .... being there is the geologists equivalent of sitting under Iaacc Newton's own apple tree! 🙂

Ps Gubbio is well worth a visit in its own right even if you're not into rocks ... great old quarter with interesting architecture, great bars and eating places.
Pps .. I did say it was obscure ... but hoped the clues and google might do the trick 🙂
