#1: The confluence point lies on this dirt road

(visited by Ross Finlayson)

05-Jun-2014 -- It's rare that a Degree Confluence Point lies directly on a road. You might expect to see this in an urban area, or on a wide open plain (where roads are sometimes laid out to follow lines of latitude and longitude). It's even rarer, however, to find this in an alpine region - which makes this confluence point quite remarkable. Surprisingly, however, despite being trivial to reach, this confluence point has been visited only once before - by Eric and Michelle Lincoln, almost 13 years ago.

Driving north on US 93, I crossed the Salmon River about 5 miles north of the 45 degree latitude line, then backtracked south along the western side of the Salmon River. I then climbed up a long, steep gravel road towards Williams Lake. (This road was wide and smooth, but had no guard rail, despite the sheer drop-off on the left-hand side - so it was somewhat unnerving to drive.)

The Lincolns noted that the best way to reach the confluence point was to wind around the western edge of Williams Lake, thereby approaching the point from the west. From satellite imagery, I noted the junction at [44.999768,-114.026258], so I set this as a waypoint, and my GPS dutifully directed me to this point. (This is about 1 mile from the confluence point.) I then turned onto a smaller dirt road (signed as being towards "Rattlesnake Creek") that was not known to my GPS. This road was narrow, but easily driveable, and it took me directly to the confluence point.

Here is a remote-controlled aerial video of this confluence point.
