Not sure what happened..

When I first started walking more intentionally around my local area, this is one of those routes I really wish I'd known about when I lived a 10 minutes walk away! I might have got into this a lot sooner.

I've been taking pictures of these stepping stones regularly for about 10 years now, and have built up quite a collection, but sometime last year that stone on the right of the picture got broken. Definitely over a year ago but not sure how long before that.
