Pressure | 8B Boulder problem at Dumbarton Rock

First ascent.

Perhaps the prime example of Dave's attritional approach, however, was his ascent of Pressure (8b) in 2005, taking a line through the desperate, horizontal terrain of the black cave of the Eagle Boulder - the apex of an epic siege across 100 days and four years. Deemed impossible by many strong boulderers, Dave invoked the spirit of Andy Dufresne in the film The Shawshank Redemption to understand that all it takes, really, is pressure and time. [1]
