Clark gained preservation of what became Yosemite National Park, and raised awareness of the wilderness, setting an example for the preservation of other ecosystems and wilderness areas. Today, the Giant Sequoia that would have been the first of its kind to be seen by Clark at the Mariposa Grove is named and marked "Galen Clark Tree" (240 feet; diameter 15.3 at 10 feet above mean base) in memory of his contribution to the preservation of the Giant Sequoia ecosystem and the idea of the national park.[4][5] Mount Clark and the Clark Range, located east of Yosemite Valley, were named in his honor.[6]
