Very slippery around there at the moment and the 'stream' in the dip has water which shows you how wet it has been. The boggy end will no doubt be a quagmire after the snow and thaw. (There used to be a pond many years ago but was filled in, I think sometime in the 80s - no doubt some health and safety assessment deemed it a drowning risk. Now you are only likely to slip in the mud a break a limb. Huge improvement...)
