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

This canyon is a drainage which drops down into the valley behind the Stawamus Chief. 2 stars at best, it is really only of interest as a canyon if you happen to be up on that ridge and looking for a fun way to get down. Although the views of the backside of the Chief are excellent.

Approach

Take the gondola to the top and walk down the access road until you are near the canyon, then follow the creek to the first rappel. If the gondola is not running, leave one car at the Stawamus Chief Campground parking lot, then drive up the Shannon FSR to the locked gate. Park at the gate and walk along the access road until you are close to the start of the canyon and enter the forest and follow the creek.

Descent

At high flow, this can be an unpleasant experience. At low flow it is relatively simple. All rappels are bolted other than the first one which is off a tree. Slippery rock and lots of difficult rope pulls.

Exit

Two options. First option is to hike NE and back up to the access road and walk back to the top car or gondola. Alternatively enter the forest and descend down towards Olsen creek. There is an old logging road overgrown with alder which leads west paralleling Olsen Creek to the trail system which leads back down to the parking at the Stawamus Campground parking lot.
