Ascent Trip Report

Easy hike from the Canadian side ....... a very friendly border.

This TR is for "Boundary 492.7" and "Boundary 496.8", both peaks can be easily visited in one outing from the same TH at "marker 494.9". The directions to the TH are provided below. I didn't have my GPS with me to confirm the coordinates.

From the TH follow the Canada/USA Boundary Line:
...... Eastbound (abt 2 miles) to "Boundary 492.7", the actual orange survey marker is on a tree on the Canadian side of the swath at a height-of-land, or
...... Westbound (abt 1.2 miles) to "Boundary 496.8", the orange survey marker is on the USA side. See the "Boundary 496.8" TR for an alternate easier route.

The Boundary Line of the two countries is on a wide-open-swath through the woods, it has an unmaintained trail (a vehicle track), very wet/flooded/muddy in a number of places (requiring detours). The overall footing is good and the going is fairly easy. Look for the respective Highpoint in the open swath in front of the Survey Marker.
Numerous orange "Survey Markers" (with the stamped mileage) are nailed to the trees along the Boundary swath (on Canadian or USA sides). I do not believe the distances between Boundary Monuments is the same, I did not see Monument 493 although the Goggle map shows it being there.
You will see numerous yellow plastic signs "Interdits" and a number of ladders to hunters-tree-perches on the Canadian side. Not the case on the USA side, clean of signs and little evidence of hunters.
This trip reminded me of my hike to "Border Monuments 445-446 Peak" in 1995, where I saw "moose traps" for the very first time ....... for a good read see its TR dated 1995-09-24c.

The TH is at the dead-end of Chemin Cote-du-Calvaire, the Canada/USA Boundary Line at mile "marker 494.9", a wide swath in the woods.
To get here from Sherbrooke travel East on Hwy #112 towards East Angus, turn south on #253 and find your way to Saint-Isidore-de-Clifton (d'auckland). In the center of the village drive east on Chemin du 9ieme Rang for 10.5km to its end ....... the gravel road continues straight ahead as Cote-du-Calvaire, to the right is Chemin Labranche and on the corner a large white cross. Continue straight (east) on Cote-du-Calvaire for 1.5km to the dead-end at the Canada/USA boundary Line. To the right (150M) is Monument 495, so I have therefore marked this dead-end as "Marker 494.9". This is the TH, ample parking ...... very friendly neighbors indeed.
