Classic Cascade Climbs features more than 100 climbing routes across 70-plus peaks--from renowned alpine routes to challenging trad climbs, as well as a handful of sport, ice, and crag options. To determine if it was a "classic" each route was judged on the following criteria: overall quality, popularity, accessibility, style, and historical importance. Climbing beta includes:

• Peak and prominence elevations and type of rock
• Grade, approach, route, descent descriptions
• Detailed photo-based route overlays and topo maps
• Pitch-by-pitch details, estimated time, recommended equipment
• Required permits and other special considerations
• Selected history including first ascents
