I spent last weekend in the Welsh mountains, assisting at the Welsh Rally GB, an international motoring event. And to my entire lack of surprise it was rather wet!
Underfoot was several inches of mud, as people and cars churned the soil of an enormous conifer plantation.

I hope that a geologist can tell me why, although it may need a soil biologist to answer, but what caught my eye was that the mud was silver coloured. Not grey, but an almost bright off-white, even in the overcast weather. Was this due to the predominate tree in the forest, the firs, or the underlying rock, which may have been slate?

Almost surely from breakdown of the local rock--maybe mica schist. Here's a UK soil observatory site: http://www.ukso.org/pmm/home.html

Silver mud, silver mud
Its racing time in the Welsh mountains.
Feel it squish. Squishy, squish.
Soon it will be racing day.

(to the tune of Silver Bells) :D

Squish? SQUISH??? Have you ever seen a forest stage rally? On a wet day? In Wales?

There's so much mud it even gets on the lens of the helicopter camera!

PS Thanks, Grapes, that site clearly is most useful, but it needs the interpretation that a specialist could give - as I feared a soil ecologist is needed! J.
