✦ Synopsis
A tuff filled volcanic vent which outcrops among Tremadocian rocks about 2 miles southwest of Blaenau Ffestiniog is described. The vent is correlated with the lower Caradocian Moelwyn Volcanic Series. Comparisons are drawn between this vent and the fissures from which the dominantly ignimbritic rocks of the Snowdon Volcanic Series were erupted and these are extended to account for lithological differences between the Snowdon and Moelwyn volcanic rocks.
