Hit the Buttermilks at 0600, before the heat, with Colby, a PCT hiker and climber who wanted to see them. I got up about 6 problems total, two of them after many tries. Another two defeated me, one a beefy overhanging jug haul. My best victory was an arete with very thin feet, the first good hand about ten feet up. It finally went with a right foot hooked around the arete and two tenuous pinches before reaching the good hold. Even after that, thin moves to the top. Very satisfying.
