Ascent Trip Report

With nothing to do on the weekend, I decided to go grab two 1000' prominence summits that had been sitting in my to-do list for a while. The weather didn't look promising but that's not too much of a hassle. On Saturday morning, I woke up around 08:00, prepared a planning, read a bit, and left home around 10:00. I made my way to HWY 10, heading west. I took exit 68 and headed north on HWY 139, turning left on HWY 112 in Granby. In Saint-Paul-d'Abbotsford, I took a right on rue Southière and then turned left on rue du Sommet. I found the chain-gated trail between two houses mentioned in Jean-Philippe Lavoie-Morin's trip report and parked on the wide shoulder.

I got ready and headed off past the gate but I could hear power tools in the clearing further ahead. Not wanting to be turned back by the owner, I angled in the woods and went in a rough line towards the summit. The forest was very sparse and I soon reached plastic piping for a sugar shack. I made my way through the very low hung pipe system, often able to go over them. At first the slope was gentle but it quickly became moderate. I crossed a few faint ATV trails everywhere but they tended to run perpendicular to the slope. The ground was wet and it was raining but I was mostly sheltered under the canopy. My pants got damp quite quickly when I reached steeper sections where ferns grew in abundance.

When I reached the main forest trail, I decided to follow it west a bit to see if I could find some flagging but when I couldn't find anything, I went straight uphill. It got quite steep and I had to use my hands in a few spots but nothing daunting. I reached a false summit just below the main bump and was faced with a deep trough where I had to find a decent way down, circling around west. From there it was only a few more meters up to a somewhat open summit with a bed of high ferns. I got quite soaked just walking around to the high spot where a faded pink flag was tied around a small tree.

I could see a herd path heading east from the summit and decided to follow it for a while. It quickly became evident I could simply head downhill as the slope seemed gentler than on my ascent and I eventually found a string of flags tied around trees in the piping system that came very close to the summit on this flank. I followed some nice gullies that made the going quite easy but I still had to tread lightly on the smooth rocks and wet branches. I spotted some run down shacks in the woods that I had seen on the ascent and aimed for that and then descended back to the flat forest trail near the houses at the bottom.

From there I bushwhacked my way to the gate and then dumped my gear in the car, heading off towards Frelighsburg where I would climb Le Pinacle.
