John Muir
Establishing Yosemite National Park

Muir threw himself into the preservationist role with great vigor. He envisioned the Yosemite area and the Sierra as pristine lands. He thought the greatest threat to the Yosemite area and the Sierra was domesticated livestock—especially domestic sheep, which he referred to as "hoofed locusts". In June 1889, the influential associate editor of The Century magazine, Robert Underwood Johnson, camped with Muir in Tuolumne Meadows and saw firsthand the damage a large flock of sheep had done to the grassland. Johnson agreed to publish any article Muir wrote on the subject of excluding livestock from the Sierra high country. He also agreed to use his influence to introduce a bill to Congress to make the Yosemite area into a national park, modeled after Yellowstone National Park.

On September 30, 1890, the US Congress passed a bill that essentially followed recommendations that Muir had suggested in two Century articles, "The Treasures of the Yosemite" and "Features of the Proposed National Park", both published in 1890. But to Muir's dismay, the bill left Yosemite Valley under state control, as it had been since the 1860s.
