Cardboard ice explained


THE BIG freeze continues and now even the Chet has copped it. A thick layer of ice covers just about all of the river ..in the Loddon area at least. Cardboard ice is back on the dykes and the mystery of its different layers has been explained to me (see previous post). It is due to the tide, which - I've learnt - affects even these tiny tributaries. The water freezes at high tide, then the running water beneath retreats. Sometimes this leaves a high tide layer hanging half way up the reeds. On other occasions you break a high tide layer to find a low tide layer beneath. Elementary to old Broads hands, but not alas, to me!
