Not Guilty!

A long time (late 80's) ago I worked with someone who had done some research for Calder Hall/Windscale/Sellafield on the currents in the Solway Firth. This involved a hired fishing boat, white coveralls and vast quantities of fluorescein. Imagine the hilarity in Whitehaven harbour when the boat returned glowing brightly!

I've been watching this beauty steadily grow over the last few years - this is in Sheffield, and although orange streams are common, they rarely build up deposits as fine as this one - it's ultimately coming out of a large drainpipe, but there were old coal workings about a mile away at the top of the hill above it, so it wouldn't surprise me if it came from there. But there's been a bit of local debate about whether this is some sort of flowstone, though the geology is very much sandstone and shale with ironstone nodules and coal seams around here.
