A Carved Cliff

You stand below a vertical cliff, looking out over the northern horizon, across fields and rolling hills of tall grass.

Here, someone has taken the time to chisel into the rock the head of a serpent - a companion to the one across the road to the west.

The hills continue to the east and north, while a road appears to scale the mountains to the west. Only the cliff face appears to the south and there seems no way to scale it.
