As you step aside to let a pair of bicyclists pass, a short, nearly vertical rock draws your eye to several small exposures on the hillside...
Take a look around in the 360 photo below
Image links to a 360 photo sphere hosted on Google Maps. The view shows a small outcrop sitting in leaves to the side of the trail. By rotating 180 degrees the other side of the trail can be seen to be a hill with no visible rocks. The trail continues in either direction through the mostly leafless trees under the clear blue sky.
