Crooked Thumb Peak is located in North Cascades National Park in the rugged and remote Picket Range, which is a compact gneissic sub-range of the Cascades. Crooked Thumb is situated in the Northern Pickets above the Luna Creek cirque, approximately a half mile south of Mount Challenger and a half mile north of Phantom Peak. The infrequently climbed rocky peak is made of gneiss .
The Picket Range is characterized by intense alpine scenery of jagged peaks cut by glaciers. This area is remote and any approach is long and difficult. The wet weather pattern from Pacific storms adds to the difficulties of climbing Crooked Thumb. Ice axe, rope, protection, and crampons are recommended for a multi-day expedition.
Refer to Fred Beckey's Cascade Alpine Guide, Volume 3, for information on the established climbing routes on Crooked Thumb.
