Why this matters
Key Heugh is a sea cliff composed of Carboniferous sandstone, formed around 300 to 320 million years ago through sedimentary deposition in a shallow marine environment. It is notable for its exposure of resistant rock layers that contribute to the dramatic coastal landscape of Northumberland.
