The River Clyst is one of the last tributaries to join the Exe estuary before the Exe itself joins the sea. The lowest reach of the Clyst is tidal, with exposed mud at low tide. These pictures were taken after a spell of wet weather, so the mud extended up the banks and in the neighbouring fields.
A steep bare gully was visible leading down from the field to the river. Along its middle, signs that some largeish creature had used the gully as a slide. At the time I thought it was probably a fox or a badger, but an otter could also have been about the right size. Less distinct, at least from my point of view on a footbridge over the river, I thought I could also see prints left by paws in the soft mud.
There was a similar gully directly across the water on the other bank. It too had what looked to me like hints of tracks, but even harder to make out.
