Afon Hyddgen stone row includes four stones.
The 25 stone alignments in Mid Wales like those elsewhere vary considerably, but all consist of at least three stones aligned along a common axis. Most of the alignments are of the single row type and survive mainly in clusters on the higher ground above the more intensively used land. In common with most other regions there is considerable difference in the lengths of the rows although most consist of relatively small numbers of mainly small and medium sized stones. In common with Dartmoor and Exmoor there are several examples where alignments are found in close proximity to each other.

A single stone row measuring 7m long, including four small and medium-sized stones situated near the bottom of a steep sided valley with restricted views of the landscape. Three stones are upright and stand between 0.7m and 0.13m high, the remaining stone is recumbent. The row is orientated north east to south west and stands close to a stone pair known as Cerrig Cyfammod Glyndwr.
A probable single stone row measuring 5.8m long, including at least 4 medium and large-sized stones originally standing up to 1.4m high, situated near the top of a prominent ridge. The row is orientated west to east and originally had a sea view which is now obscured by forestry.
A possible single stone row measuring 4.8m long, including one medium and two large stones situated on level ground. The stones are orientated east to west and stand at the northern end of a long mound. Whilst they may represent a structural element of the long mound the possibility that this is a stone row cannot be wholly dismissed.
A single stone row measuring 16.44m long, including 5 medium and large-sized stones situated on the brow of a north west facing slope. The row is orientated north east to south west and points towards the western side of a nearby substantial cairn. The southernmost stone has at least two cup-marks carved into its upper face.
A possible single stone row measuring at least 120m long, including three large-sized orthostats situated at the upper end of a small valley. The stones measure between 2m and 1m high and sit beside the public highway. The row is orientated ENE to WSW and stands in an area with broadly contemporary standing stone, cairns and another stone row. Proximity of the road introduces an element of uncertainty regarding identification.
A probable single stone row measuring 27.4m long that included 8 large stones situated on an elongated natural knoll. The row was orientated east to west and stood in an area with another standing stone with which it may have been directly associated and a barrow.
A single stone row measuring 6.4m long, including two medium and one large orthostats situated on a gentle east facing slope. Only the large orthostat which is propped by a substantial trigger stone remains standing and the row is orientated ESE to WNW.
A single stone row measuring 24.4m long, including at least 15 large, medium and small-sized stones situated in an elevated position on an east facing slope. The row is orientated north to south and there are several broadly contemporary cairns in the immediate vicinity. A very precise view towards Bryn y Fan is noteworthy.
A single stone row measuring 5m long, including three medium-sized stones situated near the summit of a ridge. The row is orientated north east to south west and leads from a ring barrow. Another stone row, barrow and stone circle survive in the vicinity.
A possible single stone row measuring 4.5m long, including three small-sized stones situated near the summit of a ridge. The row is orientated ESE to WNW and stands between a stone circle and barrow. Another stone row and ring barrow survive in the vicinity.
A probable single stone row measuring 13.8m long, including 4 large-sized stones situated on a terrace on an east facing slope. One stone is upright and maybe a natural boulder which was partially exposed in antiquity. The row is orientated NNE to SSW. Another probable row exists in the vicinity.
A probable single stone row measuring 8.7m long, including 4 medium and large-sized stones situated on a flat-topped ridge. All of the stones are recumbent and the row is orientated ENE to WSW. A pair of stones NNE of the row may be broadly contemporary and directly associated. Another probable row exists in the vicinity.
A probable single stone row measuring 14.6m long, including 8 small and medium-sized stones situated on a south facing slope. The stones measure up to 0.67m high but most are much smaller, and one is recumbent. The stones towards the southern end of the row are much closer together and are separated from the northern pair by a gap. The row is orientated NNE to SSW and stands in an area with broadly contemporary standing stone, cairns and another stone row.
A probable single stone row that measured 44m long, included five small and medium stones situated on a ridge. The row was orientated north to south west and has not been seen since the construction of a wind farm. The location given for the row lies under a wind farm access road.
A single stone row measuring 8.9m long, including at least 12 large, medium and small-sized stones originally standing up to 0.92m high, situated on a north east facing terrace. The row is orientated north to south and there are several broadly contemporary cairns in the immediate vicinity. A very precise view towards Cadair Idris is noteworthy and this combined with views of Breidden and Moel y Golfa imply astronomical links.
A single stone row measuring at least 16.85m long, including 8 small, medium and large-sized stones standing up to 1.54m high, situated on a south facing spur. Originally there would have been wide ranging views to the east but these are now obscured by forestry. The row is orientated NNE to SSW, may have led upslope from a cairn and has suffered considerable damage.
A single stone row that measured at least 320m long, included eight small, medium and large-sized stones situated on a south facing slope. The stones measured between 0.93m and 0.15m high and stood near the public highway. Only one stone of the recorded alignment now survives and the remainder were removed or displaced sometime after it was scheduled. The row was orientated east to west, was aligned on a cairn known as Crug y Bwdran and stood in an area with a broadly contemporary standing stone and cairns.
A single stone row measuring 5.4m long, including two medium and one large orthostats situated on a south facing slope overlooking the Elan valley. Only one stone remains standing and the row is orientated ENE to WSW.
A double stone row measuring 50m long, including at least 36 mainly small-sized stones together with some medium-sized stones situated on a natural terrace with restricted views that include a glimpse of distant Wenlock Edge. The row is orientated west to east and leads downslope from a stone circle at the western end. There is a kerbed cairn a short distance to the east.
A single stone row measuring 9.1m long, including 6 medium and large-sized stones situated on a gentle east facing slope overlooking the Elan Valley. Three stones remain standing and the others including the largest at the eastern end are recumbent. The row is orientated east to west and stands in an area with broadly contemporary standing stones and cairns.
A single stone row measuring 7.2m long, originally including 8 small and medium-sized stones situated on a south facing slope. The stones measure up to 0.52m high but most are much smaller, and four are recumbent. The row has been partially excavated although no report has been published. The row is orientated east to west and stands in an area with a broadly contemporary standing stone and several cairns.
A single stone row measuring 5.2m long, including two medium and one large orthostats situated near a rock outcrop on a gentle south east facing slope. The row is orientated north east to south west and the stone used in its construction almost certainly came from the nearby outcrop. There are extensive views only to the east.
A double stone row measuring 10m long, including 16 mainly small and some medium-sized stones situated on a gentle south facing slope. The row is orientated north to south and leads downslope from a cairn at the northern end. There are several cairns in the vicinity.
