Juggy but powerful moves. Crux somewhere around the 4th or 5th bolt
Take the trail left once you reach the spires. Scramble up and left over boulders and talus past the 5.10 toprope on the left (two bolt anchor). Fire Starter and Plane Crash are the two bolted face climbs opposite of a shallow dihedral at the top of the talus. Both routes share a two-bolt anchor.
By the descriptions and grade I think the supertopo may have mislabeled this and Fire Starter (swapped positions in the topo).
