Gaping Gill: Yorkshire's 100m Underground Waterfall
A stream drops 100 metres into a cave chamber in the Yorkshire Dales. Twice a year, caving clubs winch visitors down. Not one for the faint-hearted.
Three Counties System: Britain's Longest Cave Network
Beneath Leck Fell lies Britain's most extensive cave system, where surveyed passages cross county lines and new connections keep changing the map.
Hull Pot: Yorkshire's 18-Metre-Deep Limestone Skylight
A 91-metre limestone chasm in the Dales where a beck vanishes in summer and becomes a waterfall in winter. Here's what's actually happening.
Malham Cove's Missing Waterfall: When the River Took a Different Route
The curved limestone cliff looks built for a waterfall, and in exceptional floods it gets one. But Malham Beck sinks nearby, the Aire rises from springs to the south, and dye tracing shows the plumbing is more complicated than the textbooks claimed.
Jingling Pot: When the Entrance Is Vertical and the Rope Is Non-Negotiable
Roughly 45 metres of free-hanging descent into a shaft you'd walk past without noticing. Walkers can peer over the edge if they're careful; cavers need appropriate kit, a steady nerve, and a tolerance for the sound of falling stones.
