Boulder Problem

A short difficult route on a boulder. The best boulder problems are usually never done on a climber’s first attempt, but rather are extremely hard routes that take many attempts to work out the specific sequence of moves and to acquire the strength to do the problem. Boulder problems are rated in the USA with the V-Scale, invented by climber John Sherman, nicknamed “Vermin.” The V-Scale rates problems from VO- to V15. Boulderers often use crash pads to cushion their falls.
