Near the beginning of the year 1874, Muir buried himself into the writing and publishing of a string of articles entitled “Studies in the Sierra”. This triggered his success in publications. Despite that, he still continued his travels and he made an impact in Alaska’s history in the year 1879, by being the first white man to discover Glacier Bay. In addition, during his exploration, he had found many new species of plants. Muir married Louie Wanda Strentzel in 1880 and moved to Martinez, California where they started their little family with two daughters.

Along the years, Muir decided to pour his devotion into writing. He described his travels, explicated his naturalist philosophy and encouraged many to “climb the mountains and get their good tidings” by noting his adventures down on paper. As such, he had published 300 articles and 10 books with each and every text filled with his enthusiasm of his love to nature. This had no doubt left a huge impact of many of his readers, which included even presidents and congressmen.

The impact of Muir’s passion reached a larger pool of people when his articles were published in Century Magazine. In his articles, he emphasized on the destruction of various green-lands through the ‘over-eating’ by herds of sheep and cattle. Muir had the privilege of having the assistance of Century’s associate editor, Robert Underwood Johnson, in which both worked together to form countermeasures. Due to the undying efforts of Johnson and Muir, they managed to garner the support of Congress in the establishing of Yosemite, Sequoia, Mount Rainier, Petrified Forest and Grand Canyon national parks.
