16-Aug-2017 -- I had a free day in Great Falls, Montana, so spent a few hours visiting this ‘forgotten’ Degree Confluence Point (visited just once before, by the Hoglunds, in June 2003). The point lies in the Lewis and Clark National Forest, to the southeast of Great Falls. It’s a bit surprising that it hadn’t been visited again since 2003, because it’s quite easy to visit. Perhaps people were intimidated by the need to drive 23 miles (each-way) on gravel roads?
From US-89, I turned right onto Logging Creek Road. I then continued for 20 miles along this (gravel) road. Fortunately most of it was smooth, and I was able to drive it a reasonable speed: 30-40 miles-per-hour. I then turned left onto Divide Road, and continued for another 3 miles, crossing over a pass at around 7280 feet elevation. Just 0.2 miles north of the point, there was a doubletrack road that took me directly to the point!
It’s unusual to find that a Degree Confluence Point lies exactly on a roadway. You are most likely to see this in an urban or suburban setting. It is very unusual to see this in an alpine region. This is only the second time that I’ve seen an alpine Degree Confluence Point lie exactly on a road; the other instance being 45°N 114°W, in neighboring Idaho.
Here is a remote-controlled aerial video of this confluence point.
