Ogof Pont Gam Description

Ogof Pont Gam is a recently discovered upper entrance to the well known cave Ogof Nant Rhin, that resurges in the Clydach Gorge. The entrance is found on the far bank of a small stream just after a small bridge (Pont Gam) on the old Heads of the Valleys Road (map). The cave is on private land, permission should be sought from the house opposite, do not park on the private parking spaces outside the house, instead park lower down the road and walk back up to the cave. This is a tight arduous cave with three pitches that drops into Aven D'Oznog at the end of Ogof Nant Rhin. The cave starts as a tight grovel in liquid mud, a few metres of flat out crawls then lead to a tight sharp section of rift passage that leads to the first pitch (15m rigged from two hangers with natural back up). The pitch drops into D'Ybot chambers with some fine calcite deposits and an interesting rock bridge that act as short respite from thrutching. The way on is a is to follow the tight rift passage that forks off on the left, which drops into a small chamber near the head of the second pitch (10m rigged from naturals). A short tight crawl then leads to the third pitch (20m rigged from 3 hangers) which drops into the impressive Aven D'Oznog at the end of Ogof Nant Rhin. The sharp and tight nature of this cave means that is quite a 'collectors item'.
