It’s been many years since I’ve seen cracks such as these! Take another look.
A squirrel could lose a paw down a crack this wide! We had rain Monday and Tuesday, but it doesn’t seem to have made a bit of difference to these trees.
This old squirrel hopes you humans see the benefits of leaving leaf litter in place, or putting down your human mulch. It’s not just for hiding acorns, you know! (And give your street trees a long sprinkle if you can, please.)
