Ascent Trip Report

A road walk and short bushwacks to 2 peaks ...... 4km, 1h45 hours including all of the checking around.

This Mountain is in the Parc Regional des Appalaches. I went to the Accueil for the Secteur Montagne Grande Coulee, on the north side of the Mountain, where I procured an excellent topographic map of the Parc. By the way the map address given in PB's data page is that of the Parc map that I picked up at the Accueil.

For this Mountain PB shows the Peak to be home to 3 Peaks (Grande Coulee, Montagne du Siexieme and Montagne du Siexieme-East Slope, the Montmagny CoHP). No question this is in error, Montagne du Siexieme is located much south of here (3.6km, see the driving directions below) and is not even mentioned in the Parc's map.
I visited Montagne du Siexieme on the way back all as per this TR and added it to PB as a provisional Peak for Greg's approval.

This Mountain is home to 2 Peaks ....... Montagne Grande Coulee and Montagne Grande Coulee-East Slope, the Montmagny CoHP.
I will inform Greg of my findings for his pursual.

My approach was from the south. From the Saint-Philemon, intersection 216/281, I drove south on 281 for 8.2km to a left on Rang St-Arthur, 1.4km left on an unsigned gravel road (signs "Le Chemin des Parcs #14 ..... a connector Parc trail from Massif du Sud to Des Appalaches).
I drove this unsigned gravel road as it winds/climbs to the ridge of Montagne du Siexieme at 2.4km (on the left is a lesser road that follows the ridge to the west), I stayed right on the main road (ignored new logging road at 1.3km to the right) for 1.6km to the start of Parc Regional Des Appalaches, a large Parc sign gives trail information with the summit at 2km.
I parked here, this was my TH. Most of the road to here is fairly good, only some short steep sections.

I continued/walked the gravel road to the summit of Grande Coulee (stretches of road are rough and steep) ....... arriving at the Communication Tower. The road continues/descends on the north side.
The Tower base has been built-up and is the present high ground of the area however not natural, there is a large clearing around the Tower. To the northwest beside the road at 100M are 2 man made bumps with old foundations (the Ski Resort on the north side of Montagne Grande Coulee has long been abandoned), near-by is contending high ground. Also due north of the Tower past the clearing (inside the woods) is contending high ground.
PB puts the Montmagny CoHP to the northeast of the Tower.

MONTAGNE GRANDE COULEE
I checked out the area, going to all possible high spots, I concluded that the present natural HP for Grande Coulee is the rock outcrop (to the northwest of the Tower at 80 yards) just before the 2 man made bumps, left of the road. GPS 46.67654,-70.35310.
Behind this spot in the woods is an old ski sign, 7M to the right inside the vegetation is a Quebec Government Survey Marker ...... a large tall wooden post, north side engraved "RV11 XLV1 11", south side engraved "4C ARSENAULT A G20". I do not know its significance.
I should note that the immediate rock around the built up Tower and the area to the north, where I chose the spot for the Montmagny CoHP (Montagne Grande Coulee - East Slope) as per below vie for the HP of Grande Coulee.

MONTAGNE GRANDE COULEE - EAST SLOPE
I chose my spot for the Montmagny CoHP north of the Communication Tower, beyond the clearing inside the woods at about 80M, GPS 46.67690,-70.35155. I added orange flag tape to my spot. The PB coordinates puts the spot in a much lower elevation, in fact my chosen spot for the CoHP contends for the HP of Montagne Grande Coulee.
I must note that it was impossible for me to locate the Co Line, I stomped the area to ensure the high ground.

MONTAGNE DU SIEXIEME
I visited this summit on my way back from Grande Coulee. The Montagne du Siexieme ridge has 3-780M contours, I went to the furthest east area only.
From the top of the Siexieme ridge, at its junction with the lesser road at 2.4km from Rang St-Arthur (per the above driving directions) I drove east 250M to a woods track on the right that climbs to a large clearing and the obvious summit at 100M ...... a rock outcrop, GPS 46.65740,-70.35970. A hunters stand is near by at the edges of the woods.
In checking out the area I found old steel rods embedded in rock, evidence, of what I believe, old Tower construction.
