And over the mossy wall the sun-drenched meadow

... runs down to the marsh - the very tip of Cors Caron. A beautiful still morning - although perhaps sun-drenched is a small exaggeration given the time of the year as evidences by the bare trees, and - alright - it isn't actually a meadow - scarcely a field, given its inclination (in both senses of the word) to the boggy marsh.
Can't argue with the moss or the wall, though!
