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.

This stream section provides valuable information of dense turbidite/shale sequence, demonstrating the base of the member and good sections in the underlying Pibwr mudstones, which shows trilobite faunas representative of major ecological changes related to water depth and oxygenation around 500 million years ago. Trilobites are the fossilized remains of a new extinct group of sea-living arthropods, which have been recorded from this site and helped geologists understand conditions of the sea bed during the accumulation of sediment. The rich fossil assemblage has also enabled geologists to compare this section with rocks of a similar age all through South wales and the rest of the British Isles. [2]

A site of special scientific interest (SSSI) in Great Britain or an area of special scientific interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I".
