However, Thomas Morgan suggested the name may be interpreted as a place where "the way (referring to the ancient mountain trackway) rises abruptly", deriving from eb- ("an issuing out") and -hynt (a "way" or "course").

The northern and western escarpment of Mynydd Epynt is formed from a suite of rocks assigned to the Ludlow stage of the late Silurian and which include the Temeside Mudstone, the Tilestones, the Cae'r Mynach, Fibua, Aberedw, Cwm Craig Ddu and Irfon Formations.

Modern archaeologists have surveyed the sites at Ynys Hir, Cornelau Uchaf and Twyn y Post, including what has since been described as a "prehistoric monument complex".

[7] Many of the features on Mynydd Epynt are known to be Bronze Age in origin, but the diversity of these monuments suggest they did not share a common purpose and that there were numerous phases of construction, in different historical eras.

These older sites were either reincorporated or left undisturbed, demonstrating a continued understanding of their importance and a respect for the beliefs of previous generations and cultures.

[11] The inns were part of an active Welsh-speaking community, with a school, church, and numerous chapels holding regular cultural events such as Eisteddfodau and Gymanfa Ganu.

The Fighting In Built Up Areas zone (FIBUA) saw the construction of many mock buildings, including a fake chapel with imitation gravestones.

[21] Unlike the Isle of Man TT races, which are free to attend, the organisers had already started to sell admission tickets via their website for the multi-category event over a long weekend.

[17][19][22] Musician Gruff Rhys has a song called "Epynt" after the mountain, which features on his first solo album Yr Atal Genhedlaeth.
