Charles Lindbergh became actively involved in the preservation of Humpback whales and worked with local residents, Pryor, and humanitarian Laurance Rockefeller to extend Haleakala National Park to include Kipahulu Valley, in large part to protect the region’s native species. While intensely private about his family—which went on to include 5 children and 10 grandchildren—Lindbergh was vocal about his love of Hana, once writing that “there is nothing quite comparable when you think of the waterfalls, natural swimming pools, and the ocean beyond.” According to biographer Leonard Mosley—who penned Lindbergh: A Biography—Hana “was both a haven and nest” for Charles and Anne, a place “where they had never felt safer or closer to each other.”
