Potholing is caving. Caving is the generic term for exploration of underground passageways, and involves walking or crawling, with the odd climb or descent, usually by ladder. Potholes are straighter, vertical holes formed by water in limestone areas. It involves going up and down ropes, using ‘SRT’ (Single Rope Technique) The club owns SRT kits, which comprise of an array of pulleys, jammers and harnesses (see gear and the club’s SRT guide in resources). Members are fully trained before being let loose down a pothole. Not that we’d let you go down loose.
