Two metres of a  green painted lateral channel marker has been washed up at N 50˚47.143″ x W 001˚24.449″ (20 feet from the Egg). These posts are made from boughs of willow driven into the mud to mark the starboard edge of the winding navigable water. I found a further shorter section upriver, as well as a fragment of green painted bark around 100 metres from the main section of post. Erosion, accidental knocks and wood  rot play their part in the ever changing changing shape of the local scene.
