2. A cairn set on the summit of Cader Bronwen. Diameter 23m, height 1.6m. A small modern cairn has been built on the flattened top. About 9m to the south-west is a large natural boulder. It is difficult to identify which feature is Bwrdd Arthur, but this is probably the boulder or less likely a nearby rock outcrop. Boulder measures 3m long, 2m wide, 1.1m high

3. Large ?platform cairn c. 23m diam x up to 2m high. Most pronounced on E side. Large modern cairn in centre. Level top possibly slightly spread to W. Probably constructed on a natural rock outcrop. Large natural boulder to S is exactly that - no indication that it was ever upright
