Spius Creek was good fun! It's a remote +20 km run, flows from the south into the Nicola River, west of Merritt, dissecting the triangle formed by Coquihalla and Fraser Canyon. Thanks to Sandy for showing us this great run!
At the high water level this weekend Spius had several III+ bits and one IV- canyon section (Big Box Canyon), the latter is a mandatory scout which required some scrambling up a steep hill to peek into the canyon and make sure it was free of wood.
In total there are 3 canyons, the Upper (a short squeeze between cliffs), Big Box Canyon (the mandatory scout and about 500 meter long) and Little Box Canyon (nothing much - can be seen from the shuttle road). Below the confluence with Prospect Creek between the Upper and Big Box Canyons is a busy class III+ hole/boulder garden section There were also two log jams that demanded attention.
