The boulders along the upper Sabrina Basin trails in the John Muir Wilderness offer quality problems on excellent granite: great cracks, chicken-head tufts, crimpers, slopers and aretes abound. Of course the Sierras are full of areas like this, and Bishop's treasures are right next-door, so this addition is mainly just an excuse to bring those climbing shoes along if you're going to these amazing lakes for some scenery or fishing (both superb) or making your way up to the peaks of the Evolution group (really, really superb!).
Park at the "official" parking area at the end of the Sabrina Basin road (to Buttermilks). Hike ~4 miles into the upper basin. From Blue Lake: take the fork towards Donkey Lake to find more crack and high-ball problems; take the right fork towards Midnight Lake for more overhung, low-ball, and traversing terrain. The rock along the trails is just the tip-of-the-berg as many problems lay tucked away above your path. Please RESPECT this wilderness, it receives a lot of traffic: please don't use chalk, don't trample fragile alpine vegetation, and Leave No Trace.
It would be good to have more detail - How about adding specific boulders as areas with photos? You allude to these in the description, but I would have expected more. Btw, great photos of the surrounding area!
