San Quintín volcanic field

In Baja California, at least 12 volcanic cones are part of the San Quintín volcanic field. These volcanoes are part of the historical and geological heritage of the region.

More than 180 thousand years ago, underwater volcanoes emerged due to sediment, ashes and lava concentrations, thus creating what today is known as San Quintín Bay.

Some of these volcanoes are located inside nature reserves protected by Terra Peninsular.

10) Monte Mazo

This volcano is located inside the Punta Mazo Nature Reserve.

Monte Mazo and Sudoeste emerged as underwater islands that trapped sediments and sand deposits, this creating a sandbar that connects both volcanoes.

  • Age: about 165 thousand years
  • Altitude: 80 meters (262.46 feet)
  • Crater’s diameter: 160 meters

Geographic location:

  • Latitude 30°21’53.38”N
  • Longitude 115°59’47.13”W
