In 1872 Congress declared the minerals under public lands free and open to exploration and purchase, and the law still stands. The episode returns to its world: Gold Rush camps writing their own claim rules, a Nevada senator who served the mining industry turning those customs into federal law, and a Congress eager to settle the West at any price.
Historians differ on whether the 1872 terms reflect capture by mining interests, given Stewart's conflicts, or simply the era's consensus that giving land away was sound policy.
