"In 2006, land was annexed from the Sonoma Developmental Center to Jack London State Historic Park. The Sonoma Developmental Center, just south of Glen Ellen, is a state-owned facility for the mentally and physically impaired. The 1,600-acre facility is part of the small town of Eldridge, with its own post office and fire department. The annexed land is accessible from the main entrance to the state park, and includes trails to an enormous redwood tree (known as Ancient Redwood), a historic orchard, and Fern Lake. The Ancient Redwood, also known as Grandmother Redwood or Grandmother Tree, is a massive first growth redwood in a quiet grove. The giant tree has a huge girth with a 14-foot diameter and is estimated to be nearly 2,000 years old. The top of the stately tree is gone, either snapped off by the 1906 earthquake or destroyed by fire. The gnarled limbs and bark are visually striking. Owls are frequently spotted in the tree. The Historic Orchard was originally planted in the early 1900s as a working farm for the residents to grow and sell fruit. The orchard encompasses 80 acres of fruit bearing trees, including apple, peach, plum, pear, prune, apricot, and cherry. Most of the original orchard remains today. Fern Lake is a gorgeous lake surrounded by rolling hills and evergreen forest. The lake was used for irrigating the orchard. This hike begins from Beauty Ranch at the entrance to Jack London State Historic Park. The route winds through redwood groves and passes London Lake en route to the Ancient Redwood. It is two miles from the trailhead to the redwood. From the redwood tree, the hike includes two options. A loop to the west circles the Historic Orchard. A trail to the east loops around Fern Lake."
