Surveys and Rigging Guides
Grade 1 elevation from 1987 Log Book, surface survey from cairn on Bunter's Bulge.
Underground Description
Entrance climb of 12m in doline appears to choke, but a small letterbox squeeze in side of shaft leads to broken pitch. First section of 6m in a rift less than 2m wide leads to a ledge, then 12m down to a floor. A slightly hammered squeeze leads into another narrow rift dropping 10m. This constricts to 20cm and then becomes totally impassable only shortly below. Squeezes are quite epic to reverse.
