Isla Tortuga is 4-km-wide volcanic island located in the Gulf of California, 40 km off the coast of Baja California.  The flat-topped summit of the 210-m-high shield volcano contains a 1-km-wide caldera.   Recent lava flows cover much of the surface of the volcano.  This 1989 view is from the west.  No historical eruptions are known from Tortuga, although fumarolic activity continues. Photo by Marjorie Summers, 1989 (Smithsonian Institution).
