Article about caving, nice to see but they do keep referring to the cavers as climbers for some reason? (They look like cavers to me  )

Of course they're climbers. Why else would they be wearing wellies?

It's the BBC.

Some of us returned today - definitely cavers! This cave was not a new discovery, rather a relatively recent French one. With not a particularly accurate survey.

This along with a number of other large chambers in Southern China were accurately laser scanned on this trip, which was led by Richard Walters and photographed by Carstan Peter and Mark Burkey.

Some Chinese cavers had joined us for a few days and where responsible for this clip I think, treat the figures with a large "pinch of salt". Now idea how the BBC got hold of it!
