A huge ancient oak tree that Jack London must have admired at Beauty Ranch in Glen Ellen is diseased and will be cut down to protect the famous writerÕs historic London Cottage. The big tree dwarfs the cottage, which is a National Historic Landmark, where Jack London lived and died. Park officials are essentially felling a diseased heritage tree in order to protect a fragile historic landmark and the visiting public. The park plans to celebrate the tree prior to cutting her down, inviting kids, art, poetry, storytelling and music. Photo: Courtesy E. Breck Parkman / ONLINE_CHECK
