A Forest Service crew hand-built a stretch of the Pacific Crest Trail across Tahoe land closed to protect it, then watched a rancher's leased sheep trample it to dust. That scene defines the externality and introduces three frameworks that let private industry mine, graze, and log federal land for almost nothing: the 1872 Mining Act, the 1934 Taylor Grazing Act, and the below-cost timber program.
Federal land is about 28 percent of the country, rounded to a third. Defenders of low grazing fees note federal allotments are lower quality, and timber loss estimates vary with accounting method. The 1872 law's 'zero royalty' refers to no production royalty, not no fees.
