Ascent Trip Report

This TR covers my trip to Mount D'Urban and Boundary Mountain 474.34. I approached form the north (Canada) starting at the TH on 10e Rang Ouest ...... 16km, 7h00 hours RT for both summits.

From the town of Chartierville, QC, jct 257/210, I drove north on 257 for 3.7km to a right turn on 10e Rang Ouest, 8.1km east to the TH on the right side. The Sentiers Frontaliers "SF9" crosses the road at this point.
Note: Just 100 meters before SF9 is a dirt road on the right that heads south then east, this unposted road is frequently used by ATV's. The SF9 crosses this road at 3 places on its way to the Boundary Line. For my return trip I descended this road and found out that a passenger car can gingerly drive this road to the 3rd SF9 crossing, thereby eliminating 4+km on the RT.
In this TR all the distances are guess-estimates and the times include all breaks, note taking, etc.

From the TH on 10e Rang Ouest I left southbound (cold, temp around 5C) on SF9 with a 1-2 inch snow cover (became 2-3 higher up) for 4.4km to the Boundary Line Swath. This trail is well blazed and easy to follow, only a few spots with some blowdown, it is however wet/muddy/rough in numerous places and it appears to get little use. It was slow going especially with the snow, It took me 2h00 hours to ascend this section.

The SF9 comes out at a spot where the Boundary Line changes direction, straight ahead at the center of the Swath is the benchmark embedded in rock "UNITED STATES/CANADA NO 575.5", at GPS 45.30510,-71.08694. The SF9 meets up with SF1 which follows the Swath in both directions. Took a break.
I would find out that the Swath condition throughout this area is exceptional clean and clear of any cuttings. The Swath is rocky in numerous places with a few ledges to deal with and its not without a number of wet boggy areas that have to be circumvented. The SF1 is little used so I would lose it at places and not at all difficult, the snow slowed the pace.

For Mount D'Urban I turned right westbound on the Swath and in .4km came to the Monument 476 (cast iron) located in a low/wet/boggy area, Hunters Stand on the Quebec side. A small BM in the base of the Monument read 2522' elevation.
I continued westbound 2km over a major bump to the summit with super open views to the west.
After checking out the area my not-too-reliable eye-level told me the HP is the rock outcrop 10 meters inside the New Hampshire woods, beside it at 5 meters is a beautiful white Canister "D'URBAN 3010", installed in 2008, numerous people signed the register.
I left the summit after 35 minute break and was back at BM 575.5 (9.2km, 4h15 hours from TH).

For Boundary Mountain 474.34 I continued eastbound on the Swath from BM 575.5 for the 1.2 km to the obvious summit (see its TR for the details).
On the way (at .4km) I came to the granite Monument 475 (GPS 45.30565,-71.08359), it has been renewed, evidenced by the engraving "1998" on the concrete base. To my surprise a flat Old Stone Marker, embedded in the ground on the USA side of Monument 475 concrete base. This flat Old Stone Marker is engraved with dated letters "NH/ME, 1858", no question that this is the NH/ME State Line and therefore the TriPoint Marker NH/ME/QC. This historical Marker was originally called the Crown Monument.
I was aware of the existence of this Marker, but I always thought that it was separate from the Monument 475, since the goggle map shows the State Line west of 475.
I should note that the surface of this Marker is below grade level and it appears that it has been recently cleaned/maintained, something like someone maintaining a flat stone grave site.

I should note that there are numerous "UNITED STATES/CANADA BM" throughout the Boundary Line section that I hiked.
I got back to BM 575.5 (11.6km, 5h30 hours from TH) and back down to the TH on 10e Rang Ouest (16km, 7h00 hours).
