204 - Steinbrückenhöhle
Pushing down the Ariston (& on & on ...) series. Basically, it goes. Now over 200m deep, 3 qms at the bottom, one of which is a 3 s drop in a wide shaft. Surveyed & derigged. Arrived at the bottom of the 2nd pitch to the sound of rushing wateer. Sprinting exit to find 2cm diameter hailstones all over the place.
