Somw sample mud marks for the Tidal Timespace: Imprints & Palimpsests project with Heather Green

I have been photographing mud marks at low tide in the Severn Estuary for the project I am doing with Heather Green. These include a lot of wader / wildfowl footprints and tracks. And other things. Here is a sample. It can become a bit compulsive. And, of course, most will be erased by the next high tide and new ones be in place after the next low tide.
