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.

Introduction[edit]

While Idaho is known for a lot of things canyoneering is usually not one of them. But the state does hold a few gems with poison creek being arguably the best technical slot canyon in Idaho. It's worth doing if you have the chance but its not for everyone, because its wet and has a lot of poison ivy, poison oak, stinging nettle, and thick blackberry bushes. So if you decide to do it, be careful and dress accordingly.

Approach[edit]

Park on Sand Basin Road (43.4953644, -116.9625189) and head southeast across until you reach the main canyon (don't be deceived by little poison creek). Then descend down into the canyon on a faint game trail (43.4893091, -116.9552783), then bushwack downstream until you reach the narrows.

Descent[edit]

Follow the stream down the narrows until you reach rappel 1 (20ish feet), the continue down until you reach rappel 2 (65ish feet). Swim across the pool at the bottom of rappel 2 then continue down until you reach rappel 3 (35ish feet), then follow the stream until you reach the end of the canyon. Beware this canyon has flowing water and is slippery in spots. There are obvious bouldering for building anchors for each rappel so bring webbing. Cut and take old webbing you find with you.

Exit[edit]

Once the canyon ends, take a left and follow the obvious 4x4 track back to sand basin road. Then take a left and hike up the road until you reach your car.
