Cave
Access
Situated in one of the many small shakeholes on northern flank of Foel Fraith, with a longer, rocky, depression nearby
Description
A short clamber about 4 metres deep leads to a tight muddy slot. Beyond is a hands and knees crawl past a stalagmite in the middle of the passage until it is possible to stand up about 15 metres in a small chamber with large boulders at the head of a 12 metre pitch into a large, boulder floored passage. Across from the pitch is the way on down a climb and along a passage passing an oxbow which emerges after a pitch down on the left to the sandy lower series. The passage enlarges at an eyehole into the lower series, goes up a boulder slope, and along a low passage to the head of the impressive Canyon, where the floor descends before rising, past a passage on the right, to a chamber. The right hand passage leads to much more passage, including several large chambers, and blind pitches up to 20m deep...
