Isla Tortuga volcano is a young basaltic shield volcano that forms the small 4 km wide island of the same name located 40 km off the Baja coast in the Gulf of California.
The volcano has a circular summit caldera, about 100 m deep, containing a frozen lava and several cinder cones from probably relatively recent eruptions. Young lava flows cover most of the volcano's flanks. At present, there is fumarolic activity.

Sfondo

The shield volcano was constructed during 2 north-migrating periods of activity that began with submarine eruptions and included formation of a circular tuff-ring complex enclosing the caldera.
The sides of a small volcanic horst in the center of the caldera display lava flows overlying a 2-m-thick halite bed, formed when sea water filled the caldera, creating an evaporite basin.
