I can't tell whether this is Riddler or Temporal Anomaly in Cowan's guide. The description matches Riddler best so I'll assume that's it. Another good slab route. Clipping the 3rd bolt is tough! Going straight up at this bolt is really hard - it's much easier to work up on the right.
Bolts. Bring a blue Alien for extra pro while clipping the 3rd bolt.
