At the very end of the drive to Tooth Mountain one finds this smaller stone circle
slightly different angle
And far up The Pocket, sheltered somewhat from elements and possible enemies, is the fulachai fia, where people camped and cooked. 
Farther up Tooth Mountain itself it is said there are a set of standing stones, inscribed with a text no one has been able to decipher.
I longed to go up there but the gate to the land owned by the farmer where these stones are hiding was locked. 
When a gate is merely closed, it is usually acceptable to enter, making sure to close the gate behind you. When one is locked, that is a clear message to keep out.
So I did.
