Huell explores Beauty Ranch in Sonoma Valley, also known as Valley of the Moon. The estate was once the home of Jack London, one of California's most famous authors, and his wife, Charmian. It is now part of Jack London State Historic Park. It is where he lived during the last eleven years of his life and wrote many of his most famous books, including The Call of the Wild, White Fang, and The Sea-Wolf. Charmian London's former home, the House of Happy Walls, is now a museum. Also on the property are The Cottage, the ruins of Wolf House, and the gravesites of Jack and Charmian.
