The Clach Biorach (in English, "Sharp Stone") is a three-metre Standing Stone located 1⁄4 mile (0.40 km) north-west of the village of Edderton in Easter Ross. It dates to the Bronze Age, but two Pictish-style symbols were later engraved on the north side, making it a Class I Pictish symbol stone. The symbols are a 1) double-disc with a z-rod, and 2) a salmon above.
