Stained Glass is one of the Bishop’s most iconic and photogenic boulder problems.

Sitting among the classic Buttermilk blocs, it’s famed for a sequence of skin-eating, glassy crimps that demand precision and body tension, building to a committing throw to the lip off a tiny left-hand crimp.

Technical and powerful, Stained Glass is widely regarded as one of the Buttermilks’ purest V10s — a compact masterpiece of thin granite climbing.
