At Rhydtalog there is not a great deal to see and no accessible workings. The site is mainly interesting for the reservoir having flooded the dressing floors, pumping wheelpit, engine shaft and deep adit - they can just be seen at about five foot depth below the normal water level of the reservoir. When water levels are low, the masonry of the wheelpit and the masonry of the shaft collar are exposed above water level. On the grassy flat area above the submerged remains is the circular outline of a horse whim, a large wet hollow seemingly marking the site of a shaft, and ruins of the office, stores etc - and presumably including a smithy as there some coal ash there. South of the small tributary stream (the Nant Rhydtalog) is a very ruinous magazine and a couple of deep hollows - one is slighly rock cut, the other merely grassy. At least one of the two appears to be a run-in level. A leat can be discerned on the north bank of this steam a short way upstream.
It is difficult to reconcile the visible remains with the description in Hall as he wrote prior to the reservoir flooding much of the site.
The remains of East Rhydtalog are very scant and seem to mostly lie beneath normal water level of the reservoir.
Access is lengthy to Rhydtalog - its a fair walk from the old chapel. I was fortunate enough to meet the farmer who did let me drive down but he did explain that the gates are locked when he is not tending his stock - so if you drive down without checking, you may get locked in!
