The mystery of the culvert ...

On a recent trip to research my latest novel, I visited a remote part of the countryside. In it were woods and a  stream in a deep and virtually inaccessible culvert. At its deepest part and up against a steep bank, the trees were festooned with religious icons. Nobody knew how old they were, why they were placed there or who did it. The photo shows just one, which was taken from some distance away

Suffice to say, it is manna to my inventive brain and imagination!
