This site is designated due to its geological qualities. In Wales, geological sites range from quarries to rocky outcrops and massive sea-cliffs. 30% of SSSIs in Wales are notified for geological and geomorphological features.
The site has a number of small rock outcrops including a quarry on farmland approximately and is considered to contain the best examples of Llanvirn rocks in Anglesey, a Series that is otherwise poorly represented in North Wales. Fferam-uchaf shows small but stratigraphically important outcrops, but is an important site for an understanding of Lower Ordovician palaeogeography.
