My theme for last week is "identify". Can anybody put a name to these structures, which seem to be appearing everywhere. This shot was taken in Iceland last week, but we have seen them in Norway, England and the USA, mostly on beaches, but anywhere where pebbles are available. We label them miniature cairns, but wondered if anyone knows of an official name for them.
I spotted Brenda's unfinished crossword lying on the table and thought it perfectly filled the bill for this week's theme. By the time this image is posted I am confident it will be completed - crosswords are her obsession.
