V Utahu u jezera Powell zkoušejí lezci Deep Water Solo (DWS) Dry Tool, tedy nejištěné lezení nad vodou po skále s cepíny. Podívejte se na video, jak to  dělají.

Lezou na převislém prý mizerném pískovci. Pod videem uvádějí, že s cepíny lezou jen v místech, které je obvykle pod vodou. Ta skálu vždy naruší a vyroste na ní plno řas, tak tam klasicky nejde takřka lézt, a proto to zkoušejí s cepíny. Skála nad vodou je lepší, a tam se zbraněmi prý nelezou. No posuďte sami:

In Search Of Deep Water Dry Tooling from Aaron Mulkey on Vimeo.

Aaron Mulkey continues his exploration of Lake Powell's nearly 2000 miles of shoreline for Deep Water Dry Tooling. This time he brings partners Josh Wagner and Laura Chimielewski who are blown away how good the climbing is.

I want everyone to know, the walls being climbed are typically under water and the rock is very weak sandstone since it's usually under water. When the damn was built it filled up over 2000 miles of canyon walls with water. Because these walls are typically underwater the algae growth on the surface of the rock makes it nearly impossible to climb with your hands. Each time these walls go under water they shed rock and grow more algae. The rock above water line is much better and we do not climb on those with tools.
