California's Joshua Tree is a trad climbing proving ground, home to old school test pieces and classic crack climbs by the score. Professional climbers Matt Segal and Will Stanhope have their sights set on two of its most notorious finger cracks. First up is the tough and terrifying John Bachar route 'Acid Crack' (5.12d), which features thin, strenuous climbing with sections of poor protection. On a whole different level to 'Acid Crack' however is the boy's main project; 'Stingray.' Weighing in at 5.13d and featuring one of the most unpleasant crux sequences around, 'Stingray' is, by some distance, the area's hardest route. Matt and Will get their trad climbing heads firmly engaged as they set to work on this rarely repeated classic. Matt Segal Fingerlocks To Victory On 'Stingray' (5.13d) | Hardliners, Ep. 4
