These will turn bright red in a few weeks, but still won't be edible. The tree is called a Mountin Ash or Rowan.
If I didn't know it was normal for these trees to grow like this, I'd be tempted to stand there and pick at it all day.
This crazy tree is right on the trail to upper Latourelle Falls. My kids took turns getting inside, but this one was the keeper.
This was made with my Sony Zeiss 24mm f/1.8 lens cropped to square format in post.
