The British Geological Survey have lots of wonderful open data. A favourite is their Geoscenic photo library - so much amazing historical and geological record! 😊 Here's an 1893 plate camera image of the Cuillin gabbro mountains in Skye 🤩 http://geoscenic.bgs.ac.uk/asset-bank/action/viewAsset?id=2997&index=34&total=758&view=viewSearchItem #BWPhoto #Geology #Archive
