If you look carefully, however, there's a story to be told in the bottom right of the picture because more arable fields, distinguished by their striped, 'lazy-bed' pattern, can be seen spilling across the head dyke.
These fields can only have been brought into production at a time when Glendrian's population couldn't be fed from the land within the head dyke. They were, if you like, fields of desperation, because they must have been bitterly hard to work.
Towards centre right of the picture can be seen a small waterfall. The next picture....
There is no evidence, from censuses and other documents, that Glendrian's population was unusually high any time back into the 18th century, so it is possible that these fields are much older.
A history of the clachan of Glendrian is here.
Towards the bottom of the history are two fascinating papers by Andy Carter.
Andy's family lived in Glendrian for hundreds of years.
