Buried Treasure - Hanging Rock
As Matilija reservoir slowly filled with water in 1948-1952, a Ventura County landmark was submerged. The Hanging Rock of Matilija Canyon, also referred to as Overhanging or Leaning Rock, was enjoyed for decades by residents and visitors to the resort at Matilija Hot Springs, located closely downstream. Historical photos reveal that Hanging Rock survived the blasting necessary for construction of the dam, and it now lies deeply buried beneath a half-century of fine silt deposits near the dam. Hanging Rock will one day be resurrected as sediment is removed for the deconstruction of Matilija Dam, and future generations will again be able to enjoy this historical landmark.
