You come to a very cool (if still standing) white sandstone feature directly on the ridge (photo). There is a small face to ascend to continue. There is also a long chimney on the left side of the ridge that you can traverse into. I believe it safer and quicker to rope up and climb the small face which sports a crack allowing you to place a piece of protection or two. It is best to coil the rope after this for the continuation along the ridge to the base of the 5.8 pitch. Ascend to the base of this technical section from the right side of the ridge. It is the red colored top section of the ridge.
