My son just put me on to a new app from the British Geological Survey – iGeology 3D.
It’s only available on Android (maybe it was too onerous / time-consuming / costly to develop an iphone version? not sure.)

We’re going to give it a proper test drive (walk) on Saturday – I like the idea of being able to identify what you are walking over and above, wherever you are in the UK. And with the surface landscape still available to see.

I think there is already a Geology map available for your phone from  the BGS but this adds an extra layer (excuse the pun) of interest for when you are out and about.

It also means I may write slightly more accurate descriptions of the rocks I’m trudging over in future posts!
