Cruise up the block to an intimidating bulge with a convenient bolt. A reachy move goes past this (look for the feet), find pro in the thin hands crack behind. Clip an optional bolt out to the left (part of the Dirty Black Nightmare start), and gain a good rest below a thinner crux in the namesake black streak and a well-placed bolt. Climb up more with interesting face moves and small knobs and edges with bolts and enough diagonally cracks for pro. Set a belay when the angle eases.
The next step after Clean Green Dream. Black Streak has bolts in great places on all the 5.10 sections- don't be afraid of the TP reputation. This is a great "1st 5.10" at TP.
I'm not sure on FA info; let me know if you are.
Location
Same start as 'Clean Green Dream', Black Streak begins up a block below a bulge toward the right side of Mosaic Wall. The namesake black streak is apparent. A couple of pleasant granite boulders are at the base. To descend: traverse to the Bienvenidos 2 bolt anchor and rap with a single rope, or walk off farther to the east.
Protection
Mostly draws, but you'll want nuts and mid-size cams (0.6" to 1.5", nothing bigger than #2 camalot, except maybe for anchor). 4 or 5 bolts..
