Caboose 

Caboose is a solid 10b, relative to the rest of Squamish anyway, and if you are a low 5.10 leader expect a battle. There are a lot of "tough" 10b's in Squamish: Caboose, Hand Jive, Apron Strings, The Split Pillar, Split Beaver, S&Ms Delight and Arrowroot are but a few. Anyone wishing to move up the lower 10's would do well to hop on these routes. Regardless of the outcome, much will be learned.

There are access issues at some of these routes, so please check locally before you climb them.
