Crychan Forest Tracks

Trefawr Track, a forestry road north of Cwm-coed-Aeron Farm, Llandovery, Wales, is the location of the Global Boundary Stratotype Section and Point (GSSP) which marks the boundary between the Rhuddanian and Aeronian stages of the Silurian period on the geologic time scale. The GSSP was ratified in 1984. The boundary is defined as the first appearance of the graptolite Monograptus austerus sequens (the base of the Monograptus triangulatus biozone). The section is primarily mudstone, which yields an abundance of shelly faunas. The graptolite Diplograptus elongatus occurs immediately below the boundary.

The Llandovery transmitting station is a telecommunications facility located to the north of Llandovery and east of Cynghordy, in Carmarthenshire, Wales. It has a self-supporting 40 m lattice mast erected on land that is itself about 312 m above sea level. The site was originally built by the IBA, entering service in 1968 transmitting the now-defunct 405-line VHF television system. As well as providing an ITV service to the town of Llandovery some 8 km to the south west the site also transmitted to the north east, primarily to provide a link-signal for the ITV transmitter at Llandrindod Wells. The north easterly transmission also provided the ITV service to the villages of Llanwrtyd Wells and Llangammarch Wells. When UHF 625-line colour TV came to mid Wales in the 1970s the Llandovery locality was covered by the main transmitter at Carmel and so this site was not needed as a repeater. The villages of Llanwrtyd Wells and Llangammarch Wells were subsequently covered by a UHF relay station at Llanwrtyd Wells which came into service in the early 1980s. The nearest UHF relay to the Llandovery site is at Cilycwm 5.4 km to the west. 405-line television from Llandovery was shut down in January 1985.
