Eventually, we came to a confluence with another creek and hiked just a few yards to see Boulder Falls. It was quite impressive. If you click on the picture below you can see the people on the left at the base of the upper falls.
It was at this site that we came upon a professional photographer, snapping away. I asked her if she could help us by identifying a couple of trees. Her authoritative response was, "They are evergreens; you can tell by the cones." (We were hoping for something a little more specific.)
