Muir is best known for his sojourn in Yosemite Valley from 1868 to 1874; at his urging, Congress established Yosemite National Park in October 1890.
The park, which is home to a great variety of wildlife, 100 miles of hiking and horse trails, and skies where visitors can sometimes witness the Northern Lightsmay soon be marred by oil rigs.
Muir was a wilderness explorer and was the first Euro-American to explore Glacier Bay. In 1882 John Muir co-founded the Sierra Club with Professor Henry Senger, a philologist at UC Berkeley.
While the people are banned from the more than 400 shuttered national parks, big oil and gas companies will have no trouble getting in and will continue operations as usual in 12 of the otherwise closed national parks.
