Ice and cold water, textures and colours not often seen in England. After nearly a week of hard frost, approaching -10°C overnight and hardly warmer in the daytimes, Keswick has been colder than Port Lockroy on the Antarctic Peninsular. The soft light, the colour of the ice and the sheen on the surface of the flowing but super-cooled water are all quite strange and took me back to a winters long ago when the water froze in the River Cam in Cambridge or the canals of the Amsterdam Ring.
