Since my original plan (Driving to Barrow, Alaska) seems impossible without turning the start of my world-trip into a major overland expedition, I'm trying to find out what the most northern location on the North American continent is, that can be reached by four-wheel drive.
I'm most likely looking for the name of a village/town/city or seasonal settlement, one that has roads/tracks leading to the place.
A likely candidate is Prudhoe Bay close to Deadhorse, being the start of the Dalton 'Highway' (a gravel road).
However, looking at maps, online resources, atlasses etc, I get the impression that there might be other locations with a higher latitude number? But many sources fail to list really small places/roads.
