By the 1920s and as part of the Sequoia National Forest , the area became a recreational center , reinforced by the destruction of most of the mining structures in landslides following the 1906 San Francisco earthquake . Mineral King was used as a summer camping area . Continuing until 1942 , private cabins were built in the Mineral King area , expanding the communities of Cabin Cove , Silver City , and Beulah . ( All of these communities , including Silver City , would later become part of the National Register of Historic Places ' Mineral King Road Cultural Landscape . ) In 1926 , Mineral King was declared the '' Sequoia Game Refuge '' by the United States Congress
