Why this matters
Spy Crags is a sea cliff composed of Carboniferous sandstone, formed around 300–340 million years ago through sedimentary deposition in a shallow marine environment. The feature is notable for its resistant rock layers and coastal erosion patterns typical of Northumberland's basinal geology.
