Driven past this a number of times recently (currently working nearby), and will endeavour to bring a camera with me soon and get some photos.
The Clach a’Mheirlich or ‘Thief’s Stone’ (Pictish Symbol Stone Class 1) stands in a field by the Alness to Invergordon road. On the front is an incised step symbol and on the left side what appear to be the traces of a crescent symbol with a pair of pincers below.
Park in the ‘Public slipway’ car park. The stone is about 20m into the field across the road.
