On this Earth Day, the Episcopal calendar honors John Muir and Hudson Stuck.
Muir (1838-1914) was a Scottish-born American naturalist and author who advocated for wilderness preservation in the US, including Yosemite Valley, Sequoia National Park, and others. He pushed Congress for the passage of the 1890 National Park bill, wrote several books and many articles, and founded the Sierra Club. Several locations are named for him. With a deep sense of natural theology, he considered himself a disciple of Thoreau.
Stuck (1863-1920) was a London-born American missionary and social reformer, ordained in the Episcopal Church. He was a leader of the first successful climb of the mountain Denali, also known as Mount McKinley, in 1913. He had begun as a missionary in Alaska nine years before; he established a parish and hospital in Fairbanks and traveled thousands of miles each year to visit communities and missions.
