   • 2004, James Campbell, The Final Frontiersman: Heimo Korth and His Family, Alone in Alaska's Arctic Wilderness, page 65,

     Much of the land is tundra, a mass of spongy, waterlogged clumps of sphagnum moss called tussock, muskeg, hummock, or in the vernacular of old-time Alaskans “niggerheads.”

   • 2006, Kit Cain, Flying The Yukon's Bush, page 30,

     From the air, the bright green grassy floor of the tundra looks as smooth as a golf course fairway, but a closer inspection reveals peaty tussocks of crabgrass called niggerheads spaced just far enough apart for a foot to twist clumsily between. Walking on the frost-formed niggerheads is very much akin to walking across a gymnasium floor covered by thousands of glued-in-place softballs.

     This sloshing was compounded by the fact we were unable to keep in step with each other due to the many and various sized niggerheads (hard tussocks in tundra) that would attempt to roll from under us as if one was stepping on balls ranging in size from softballs to basketballs, with each step if unable (most of the time we could not) to avoid.

6. (archaic) A strong black variety of chewing tobacco, usually in twisted plug form.
