Coming down from the main summit
on Colline de la Rochelle, I drove about 2km north on 9e Rang ouest, to the junction with 11e Rang. I saw I could not park safely on the shoulder up ahead so I made this my trailhead to the high point for MRC Acton. It was raining lightly but nothing too bothersome, and I followed the road to an opening in the treeline. I went down into a sandy gully, hopping over two separate streams, before arriving at a shed that housed some maple grove equipment. I could see piping to my right but my course brought me away from the operation.
I progressed in a generally clean open forest, and ascended moderately to a higher plateau. I had a very precise waypoint marked in my GPS that sat directly on the county line and I was heading that way when, as I got closer, I saw a bump ahead and went over there. I could see that this would be obviously higher than anything further south, on the county line, as there was a significant trough in front of me before the terrain ascended higher. I headed there nonetheless and hiked all the way to my waypoint, marking it down. I was many meters lower than the previous bump, so I can confirm MRC Acton's high point is not a slope point but rather a very slight summit.
Satisfied with the visit, I started downhill back towards the trailhead. It was an uneventful short hike out back to the car where I looked at my planning and directions to the next goal, Cap de Wilson Pond
It turns out, after gaining access to some LIDAR data, that the left bump is lower than the right bump. I have to visit the correct area again.
