The porcupine is a common resident of the pine-clad buttes of Harding
County and individuals were occasionally encountered some distance from
pines. We noted porcupines almost nightly in June of 1961 along the road
that parallels the Slim Buttes to the east, and found a number that had
been struck by automobiles along this and other roadways in, or adjacent
to, wooded areas. Visher (1914:90) earlier reported _Erethizon_ from
Harding County.
