I found this captivating log cast up on the rocks on the Columbia's banks the other day while walking along the River Walk somewhere between Safeway and the Maritime Museum. I don't know that I've ever seen a log with pitted, trailing patterns quite like this. I must have seen one at some time, since I doubt that its such an exotic species that its like hasn't been found on these shores before, but I really can't place it. If anyone knows, I'd be interested in hearing your thoughts. Coming across a picturesque piece of natural art like this just added to the beauty of the day, the calm and peaceful sense of having the good fortune to be able to stroll along the banks of such a beautiful river.
