Clawdd Mawr, Bwlchgarw, the dyke runs almost straight for 192m WNW to ESE and is located roughly 15m above the floor of a narrow saddle running from Mynydd Caerau. The N. end lies at the head of a steep-sided natural gully, the S. on a steep slope. There is a gap were a track crosses it, but this appears recent. Near the N. end, the bank and ditch measure about upper 7.5m by about 1m high overall, but the earthwork steadily decrease in size towards the S. end, where it is now merely a shelf about 1.5m wide. There is no sign of stonework.
On the three first edition OS maps (1877; 1899; 1918), another track can be seen, crossing the dyke on the southern half. The current one dosesn't appear in them.
