You Know What They Say About Yellow Snow…
Okay so Matt was cycling along the Thames Path – you know – the bit just past Greenwich Yacht Club, going into Charlton, just before you get to that aggregates dock, just around the corner, when he came across some very odd, ‘huge, thick, slightly yellowy’ icicles on the bushes.
As you’ll see from the first pic, it’s only these bushes that are affected. “It was freezing cold, but not wet,” Matt says, “so all neighbouring bushes and trees were completely ice-free. Whereas these ones are not only covered in icicles, but really thick, blobby, bulbous, slightly alien-looking icicles.”
Matt – and I – would like to know what caused this phenomenon. “Also,” he adds, “if they’re not made of frozen rainwater, which would be the implication, then what are they made of? And should we be scared?”
I guess the yellow coud be all the salts and the sand that has been coming in on various ships for donkey’s years, and perhaps the wind has chilled that particular stretch more than others but in truth I don’t know. So, all you geologers out there, what gives?
In the meanwhile, you know what they say about yellow snow…
PS Word to the wise – in warmer times of the year, this little stretch of path can be quite slidey under the tyres because of all the loose sand. At the moment, I suspect said sand is actually helping….
