These bolts have been added to either McTavish (RH variation), Hangin' Round, or Chips Block. Can't really tell from the photo, but they all share the dihedral.
It is certainly on an established routes and interrupts climbing in the middle of a pitch where perfect natural pro exists. It also appears someone has scrubbed the moss off the rock where the rope is hanging.
I may have created some confusion. To clarify, this is not the dihedral climbed by Chip's Block. This is the dihedral 60 feet to the left and up from the rappel tree atop Half Ascent. The photo is actually taken from the rappel tree atop Half Ascent.
Also to clarify, according to the Tucker/Steele guidebook, McTavish heads up this way from the rappel tree atop Half Ascent: "From the point where Half-Ascent gains the lower left-hand edge of the large slab (block), use edges and ledges to zig-zag a course for a right-leaning ceiling some 40 feet up and left."
With clarification from guidebook author Steve Tucker, it seems quite certain that the Chouinard route McTavish climbs up to and through the roof shown in this photo. Please see a topo for McTavish here
Fortunately, the individual who placed the bolts on McTavish has committed to removing them. Stay tuned.
