Deep-water soloing

Deep-water soloing (DWS), also known as psicobloc, is a form of solo rock climbing that relies solely upon the presence of water at the base of a climb to protect against injury from fallings from the generally high difficulty routes. While typically practiced on sea cliffs at high tide, it can also be done on climbs above reservoirs, rivers, and even swimming pools.

This type of climbing is most notably practiced on the coasts of Dorset, Devon and Majorca, but also in the Calanques near Marseille, around the Southern Pembrokeshire coast, parts of Ireland, Sardinia,Spain, Greece, the lakes of Central Texas, and many other areas.

Often a dinghy is used to pick up the fallen climber as a fall from a taller route can still knock him/her out, causing them to drown.

Liquid chalk is normally used in place of a chalk bag as it removes the wastage of loose chalk involved during a fall. Some DWS climbers apply liquid chalk in a line on their forearms so that they may rechalk during the climb. Synthetic shoes are also preferable to leather constructed ones as they will not shrink when wet.

The practice of deep-water soloing in Majorca has its roots in the late 1970s. In 1978, Miquel Riera became frustrated with the aid climbing routes in his local area, so he went to Porto Pi, Palma with his friends Jaume Payeras, Eduardo Moreno and Pau Bover in order to find routes that they could free climb. This became Majorca's first bouldering venue, and as time went Riera progressed onto the short sea cliffs near there. It was named "Psicobloc", which, when translated literally into English, means "Psycho Bouldering".

During the 1980s psicobloc was overshadowed by sport climbing, which was growing greatly in popularity, but this did not stop Riera from continuing his obsession, as he put up many new routes and published articles in the Spanish climbing press.
