The trip to Mount Rainier had played a role in reinvigorating Muir and convincing him to rededicate his life to the preservation of nature as national parks. At the time national forests, called forest reserves at first, were being created throughout the American West, under the utilitarian conservation-through-use view of Gifford Pinchot. Muir came to be known as a preservationist. He wanted nature preserved under the more protected status of national parks. But during the 1890s there was more public support for creating national forests than national parks. During that decade, Muir and his supporters were only able to protect one national forest as a national park. When the Pacific Forest Reserve was created in 1893, Muir quickly persuaded the newly formed Sierra Club to support a movement to protect Rainier as a national park. Other groups soon joined, such as the National Geographic Society and scientific associations wanting Mount Rainier preserved as a place to study volcanism and glaciology. Commercial leaders in Tacoma and Seattle were also in support, as was the Northern Pacific Railway. The effort lasted over five years and involved six different attempts to push a bill through Congress. Congress eventually agreed, but only after acquiring assurances that none of the new park was suitable for farming or mining and that no federal appropriations would be necessary for its management.
