The vertical crack in the middle (behind and just left of the dog) is the "direct start" to the Arch Rock route. It is a tough 5.9+ start to reach the nice ledge with the small bush, but it protects okay. The much easier "regular" start is about 12 feet to the left of this crack (see other picture). The regular start angles up and left (5.5?) until it reaches this lower ledge, then you traverse (walk) back right along the ledge until you get to the small bush in this picture. The rest of pitch one goes up the crack behind the small bush.
