Ascent Trip Report

Gabriel Couet's recent yeoman's research has found many elevation discrepancies in the PB data base as it applies to the MRC and Provincial Park HPs, the MRC Acton HP being one of them. He has brought this to Greg's attention who will be addressing the discrepancies (I visited the original MRC Acton HP back in 2010 all as per my TR).
In the meantime Gabriel has added and visited the new MRC Acton HP (prov) all as noted in his TR dated 2017-05-07 (why he's named it "Rochelle (Acton bump)" is puzzling to me).
It took me 2 visits to successfully complete the new MRC Acton HP, all as per this one only TR. Also this TR attempts to add information to Gabriel's TR, it is not a stand alone TR and one must read Gabriel.

There are 2 candidate high point areas (west and east) that must be visited - both easily done with one visit.

VISIT #1 DATED 2017-05-12 ..... successful visit to the west area only, 1.8km, 140' gain, 45 min RT.
Rose and I came here to bag the new Acton HP, armed with Gabriel's TR but without doing my own personal due diligence. I thought I did-so successfully until I sat down to enter this TR - the MyTopo map told me otherwise.

The new Acton HP has two 300 meter contours inside the south county line. Therefore according to the rules Acton has 2 candidate high point areas and one needs to visit both in order to claim it as successful. I only went to the west area and will have to go back. At this first visit it was nice to see, as Gabriel reports, that the HP of the west candidate area is an actual bump and not just a slope. Hopefully we'll find the same at the east area.
The MyTopo maps shows the main body of the 300 meter contour to be in MRC DU VAL-SAINT-FRANCOIS with its northern end spilling over into MRC D'ACTON. The contour is best described as the shape of an inverted udder with its two teats in MRC D'ACTON (west and east, about 350 meters apart).

We parked at Gabriel's spot (JCT 10e/11e Rang) and more or less followed his footsteps to the west summit area. From the parking spot it is 200 meters north on 10e Rang to the E-W Acton/Val-Saint-Francois County Line, signs here read "Bethaine" and "Sainte-Anne-de-la-Rochelle", where a trail of sorts on the right heads east.
At about 100 meters east of 10e Rang the trail comes to a shed (more or less on the E-W County Line). Here I picked up a pink blazed tree line (pink flag tape) immediately left of the shed. This tree line is immediately north-of (left, just meters away from) a large network of blue plastic tubing for a Maple Sap collection/drainage system (which is all inside MRC du Val Saint-Francois). The route stays away from this installation.
I followed the pink blazed tree line due east (approx 350 meters from the shed) to a height-of-land at a large tree at the "west area"(45.44950,-72.41520), where the ground drops off to the east a few meters to Gabriel's way point.
From the large tree, the ridge of the "west area" heads/rises-slightly northeast to a slight bump at about 100 meters and the obvious HP for the west area (45.45021,-72.41428). I built a rock cairn and added orange tape to the spot.
This whole area is open woods with no undergrowth, easy going. I should note that my GPS tools are not the best, so my readings may be somewhat off. I backtracked to the TH, not knowing that there was an "east area" to be visited.

VISIT #2 DATED 2107-05-17 .... successful visit to the east area, 2.5km, 190' gain, 1:10 hrs RT.
I came back alone today for the "east area" (Rose not in the mood).
From the same parking spot I made my way east to the large tree at the west area, where I continued east on the pink blazed tree line 350 meters to the height-of-land (a small tree with a pink blaze) at the "east area" (45.44938,-72.41093).
On-route from the large tree the ground descends and goes over an intermediate bump before descending again to its lowest point, at a stream with a shed sitting (I think) on the Val-Saint-Francois side (right), then climbs to the height-of-land.

From the height-of-land, the ridge of this "east area" heads/rises-slightly north (similar to the west area) to a slight bump at about 150 meters and the obvious HP for the "east area" at a rock(45.45064,-72.41090). I added a few small rocks and orange flag tape to the spot.
Open woods with some rough footing (rougher than the west area).

I made an effort, with the use of my eye-level, trying to identify "the" HP with no real conclusion - only to say that they (west and east) are very close in elevation and therefore both need to be visited.
