beta

BAY-tuh
Information traditionally about a climbing route shared among climbers — where the holds are, which sequence works, where to rest. Now used widely in the outdoor culture—and beyond.
Etymology
American climbing slang, 1980s. Possibly from Betamax videotape — early climbing beta was shared via video. Or from the idea of beta-testing a route.
