Bryn Eglwys quarry

Tarrenhendre is a mountain in Snowdonia, North Wales. It is one of the Marilyns in the Cadair Idris group. Lying to the south of Cadair Idris, it and its neighbour Tarren y Gesail form the bulk of the Tarren subgroup. The Tarrens rise from the south shore of the Tal-y-llyn Lake and end at the Dyfi estuary. The summit is heathery and boggy, and has a small cairn to mark the highest point. The views are extensive to the south and east, with Plynlimon and Cardigan Bay ahead, while the north views are dominated by Cadair Idris and Maesglase to the west. Between Tarren Hendre and Tarren y Gesail lies the Bryn Eglwys quarry, and Nant Gwernol railway station on the Talyllyn Railway, in the ravine of the Nant Gwernol stream. The Tarrens can be thought of as forgotten mountains of Snowdonia, overshadowed by the popularity of Cadair Idris, occupying the sleepy south-western frontier of the Snowdonia national park.

Nant Gwernol railway station is the eastern terminus of the Talyllyn Railway near Abergynolwyn, Gwynedd in mid-Wales. It is 7 miles, 28 chains (11.83 km) from Tywyn Wharf. Nant Gwernol station was opened in 1976; before 1976 this upper part of the line had only been used for goods services.The station is built on the site of the former marshalling yard at the foot of the Alltwyllt incline, which was the first of the two inclines between the Talyllyn Railway and the Bryn Eglwys slate quarry. This site was chosen as the terminus of the passenger line, as it was the limit of locomotive working. The station building is of timber construction, based on the station building at Pendre and the original station building at Abergynolwyn. Trains only wait at the station long enough for the locomotive to run round, as there are no facilities at that point. Most trains pause at Abergynolwyn station to allow passengers time for refreshments. There is no road access to the station, though several footpaths lead off up the incline or towards the road between Bryn-Eglwys and Abergynolwyn. The station's name was taken from the nearby Nant Gwernol stream, and means "Alder Stream".

Abergynolwyn (English: Mouth of the River with a Whirlpool) is a village in southern Gwynedd, Wales, located at the confluence of the Nant Gwernol and the Afon Dysynni. The population of the community which is named after the village of Llanfihangel-y-Pennant was 339 at the 2011 census.

The Garnedd-Wen Formation (also known as the Garnedd-Wen Beds) is an Ordovician lithostratigraphic formation (a sequence of rock strata) in Mid Wales. The rock of the formation is a mixture of mudstones, siltstones, fine- to coarse-grained sandstones, greywackes and conglomerates. The formation extends from Dinas Mawddwy in the north-east to Tywyn in the south-west.

Tarren y Gesail is a mountain in Snowdonia, north Wales. It is one of the Marilyns of the Cadair Idris group. Lying to the south of Cadair Idris, it and its neighbour Tarrenhendre form the bulk of the Tarren subgroup. The Tarrens rise from the south shore of the Llyn Mwyngil (Tal-y-llyn Lake) and end at the Dyfi estuary. The summit is a grassy ridge, which has a cairn and trig point. The views are extensive to the south and east, with Plynlimon and Cardigan Bay ahead, while the north views are dominated by Cadair Idris and Maesglase to the west. Between Tarren y Gesail and Tarren Hendre lies the Bryn Eglwys quarry, and Nant Gwernol railway station on the Talyllyn Railway, in the ravine of the Nant Gwernol stream. The Tarrerns can be thought of as forgotten mountains of Snowdonia, overshadowed by the popularity of Cadair Idris, occupying the sleepy south-western frontier of the national park.

Mynydd Esgairweddan is a hill near Pennal in southern Gwynedd, Wales (grid reference SH6702). Nearby is the tiny settlement of Esgairweddan. It is very close to the site of the old Roman fort of Cefn Caer (Pennal). The area was described in the Topographical Dictionary of Wales by Samuel Lewis (published 1833) as; "A tract of hilly and rocky ground but little adapted for purposes of agriculture. The soil is thin and poor, but, in some of the lower grounds, not altogether unproductive; the declivities of the hills afford only a scanty pasturage for sheep and young cattle: peat, which forms the principal fuel of the inhabitants, is found in various parts."

Abergynolwyn railway station is a station on the Talyllyn Railway near Abergynolwyn, Gwynedd, in Mid-Wales. It is 6.55 miles (10.54 km) from Tywyn Wharf. The name 'Abergynolwyn' means 'Mouth-of-the-River-with-a-Whirlpool'.

The Cwm Ebol quarry (also known as Cwmebol quarry) was a slate quarry about 1 mile (1.6 km) north west of the village of Pennal in Mid Wales. It operated from about 1860 to about 1906. It was the last Welsh slate quarry connected only to a trans-shipment point instead of directly to a railway.

Graig Goch is a 586m high hill in the Gwynedd area in Wales and lying within Snowdonia National Park. The hill falls within the communities of Llanfihangel-y-Pennant and Corris, the summit being located in the former. The hill takes the form of a NE-SW aligned ridge with a broad top which rise to subsidiary tops either side of the main summit. These are the 540m+ top of Mynydd Cedris (OS grid ref SH 707080) and the 504m top of Mynydd Rugog (OS grid ref SH 722092). The hill’s most notable feature is the large cliff which stretches the length of its northwestern face overlooking Tal-y-llyn, in part a major rock-slope failure.

Tal-y-llyn, or Talyllyn, is a small hamlet and former parish in Gwynedd, Wales, situated at the end of Tal-y-llyn Lake close to the village of Abergynolwyn. The parish covered an area of 36,000 acres (15,000 ha). The River Dysynni flows out of the lake at this point, flowing down to enter Cardigan Bay north of Tywyn. Another lake known as Llyn y Tri Greyenyn or Llyn Bach was formerly located close to the border with the parish of Dolgellau. For much of the 19th century, and the first half of the 20th century, the predominant industry in the area was slate mining, in the quarries at Bryn Eglwys and Corris. The Talyllyn Railway was built in the 1860s to serve the quarries at Bryn Eglwys. Although this never reached the lake, and was never planned to do so, the terminus of the railway was in the parish, thereby giving the railway its name. Tourism is now one of the principle industries in the area, and the hamlet includes a hotel and public house. The parish church, St Mary's, dates from the 13th century, with the present structure dating from around 1590. It is a Grade II* listed building. John David Edwards, a cleric and hymn tune composer, is buried in the churchyard.

The Ceiswyn Formation (also known as the Ceiswyn Beds) is an Ordovician lithostratigraphic group (a sequence of rock strata) in Mid Wales. The rock of the formation is made up of interleaved beds of silty mudstones and siltstones with some sandstones and tuffs also present in small amounts. The formation runs diagonally across Mid Wales from close by Bala Lake to Cardigan Bay near Tywyn.

Llanfihangel-y-Pennant is a hamlet and wider, very sparsely populated community (which includes Abergynolwyn and Tal-y-llyn) in the Meirionnydd area of Gwynedd in Wales. It is located in the foothills of Cadair Idris, and has a population of 402, reducing to 339 at the 2011 Census.Nearby is the ruined castle of Castell y Bere, a stronghold of the Welsh princes of Gwynedd in the 13th century.
