Above the trees
Tundra is the ground past the last tree: Arctic coastal plain, Brooks Range valleys, and the short turf on Trail Ridge.

Gates of the Arctic, the Arctic National Wildlife Refuge, Kobuk Valley, and Noatak are Alaska plates with no road in. Kobuk adds an Arctic dune field, so it also sits on the dune chapter. Trail Ridge Road is the paved tundra in Rocky Mountain National Park, listed separately from the Bear Lake plate. Denali remains an alpine plate; the treeless ground there is a note, not this chapter.
