This is absolutely brilliant 🤩 Harry, your grandpa rocks!
My grandpa who is 85 started making this rock map of Scotland in 1992.He collected rocks during amateur geology trips over 30 years. He says it had to be geologically correct and also aesthetically pleasing.He asked if I could share online as He wants to go viral so please share

Continuing our tour of the UK's best geology we come to Staffa Island, Inner Hebrides.
Staffa is almost entirely formed of basalt, which erupted during the Paleogene, ~58/55m years ago, via intense volcanism during rifting associated with the opening of the North Atlantic Ocean

The Norber Erratics on the slopes of Ingleborough are great examples of glacial erratic boulders. The lower rock unit is Lower Carboniferous limestone & is in place. On the 'pedestal' is a boulder of darker Silurian sandstone (~100M years older), deposited by melting ice sheets.

Continuing our tour of the UK's geology, here's Broad Haven on the Pembrokeshire coast.
The cliffs here expose Upper Carboniferous sandstones & shales originally deposited 320–300M years ago. The compression on the rocks ~290Ma formed spectacular folds & faults, as seen here.

BGS was founded in 1835 when colonialism was widespread. We carry & acknowledge that legacy. We're working hard with our global partners to decolonise geology & ensure our past doesn’t define our future.
