Buckhorn is a Ferris-type wooden cargo vessel built by R.J. Chandler, Washington, California. It was built for the United States Shipping Board as part of the massive World War I shipbuilding effort. Like many of the shipwrecks within Mallows Bay, Buckhorn was brought to its current location in the 1920s for salvage. The vessel is now resting on its keel (bottom) and the hull (frame) is well preserved. There is light plant growth in the bow (front) and stern (back) and a colony of freshwater clams is located within the aft peak bulkhead (an upright wall at the back of the ship).
Buckhorn is notable for its iconic lone tree growing out of the stern. (Mark Losavio/NOAA)
