Welcome! Canyons in the Pacific Northwest can be different from those you might be used to. Be ready for unlinked bolts, retrievable traverse lines, and challenging aquatic environments. For more on local practices, and the best way to get started in the region, check out the WCC Safety page. Unlinked Bolts - groups should be comfortable rigging unlinked bolts, either temporarily linking them for all but the last person, or using a passive redundancy method. Most importantly, if you find two bolts side by side that are unlinked, do not add webbing to them. Linking bolts designed to be unlinked will likely cause damage during seasonal floods. Traverse Lines - many canyons are rigged to allow traverse line access to an exposed anchor station. This should be done using self-belay or team belay techniques. Do not leave fixed lines in the canyons. Challenging Environments - the highly aquatic nature of PNW canyons can surprise many. Cold temperatures, slippery rocks, loud waterfalls, and strong currents all lead to unexpected problems. Do not underestimate the need for strong team work and technical proficiency. Belays are frequently not possible. Unattended gear will sink or float away. Sliding and jumping is the cause of most major injuries, so it's critical to effectively communicating water depth & submerged hazards.
