Warning - Attention 2017-11-04

Grosse chutte de pierre au mur principal et les toits. Le secteur a besoin d'être purgé et l'équipement inspecté.

Description

On the north shore of the Lac Boisseau is a sublime south facing little crag with several high quality sport climbs. The rock type found there is absolutely unique in the Laurentians and reminds one of sandstone.
The routes are relatively short, many are slightly overhanging, and the rest are vertical.

Access:
The cliff itself is on crown land and the trail is seemingly part of the Trans Canada Trail. For now, rock climbing is allowed but is not regulated.
It seems that the land has been bought by the municipality of La conception in 2011 with the plan of transforming it into a nature Park.

Getting There

Drive:
Autoroute 15 north which becomes route 117 north at Sainte Agathe.
From the second traffic lights continue for 12.5km
Take exit left for La Conception, rue Principale (the one following the exit for the Montagne d'Argent)
Drive 0.75km and just before the bridge turn right on rue des Érables.
After 4km turn right on Chemin des Chênes.
After 7km turn right into the parking lot for Sentier Alléluia.

Approach:
From the right side of the parking lot, follow the trail down towards a log bridge. Cross the bridge and follow the creek left to the lake. Continue along the trail right, which skirts the lake's shore. You will walk through several campsites. After about 10 minutes look right and you should see the cliff a hundred feet up the slope. Look for a trail that goes up.

!!!DONT CLIMB HERE!!!

I was part of the party which witnessed the rockfall event of November 4th 2017 at Lac Boisseau. I had walked down the trail just passed the Main Wall towards Polichinelle with my partner, when behind us boulders as large as cars were raging down. Fortunately, we were all safe.

Two rockfall events occurred within less than a minute, proving the constant instability falls create.

Presence of runoff sediment showed the vulnerability of the terrain where the fallen boulders resided prior to fall. Without proper assessment of the site, this evidence suggests that the affected areas should be considered at risk for subsequent rockfall events.

Please don't climb here until an accredited authority has determine that the site is safe. Nov 5, 2017
