passage (L-R: Ritchie Simpson, Toby Speight, Jane
Stewart-Boland and David Morrison)
The underground chamber in Applecross was found by members of the caving club, Grampian Speleological Group.
The cavers enlarged a small man-sized entrance they had found, to explore a water-filled passage that led to a series of underground chambers.
David Morrison said it was "possibly the most beautifully decorated passage anywhere in Scotland".
He added: "This is a significant discovery in the context of Scottish caves and I believe we have probably found the 'master-cave' of the area."
Mr Morrison found the cave along with fellow cavers Ritchie Simpson, Toby Speight and Jane Stewart-Boland.'Underground heritage'
