Islas Marías

The Islas Marías ("Mary Islands") are an archipelago of four islands that belong to Mexico. They are located in the Pacific Ocean, some off the coast of the state of Nayarit and about southeast of the tip of Baja California. They are part of the municipality (''municipio'') of San Blas, Nayarit. The islands were used as a penal colony until February 18, 2019 when President Andrés Manuel López Obrador ordered the closure of its operation as Islas Marías Federal Prison.

The first European to discover the islands was Diego Hurtado de Mendoza, a cousin of Hernán Cortés in 1532, who gave them the name Islas Magdalenas. He found no evidence of prior habitation by the Indigenous peoples of the Americas, Native Americans.

In 2010 the archipelago was designated the Islas Marías Biosphere Reserve by UNESCO.

Geography

The islands have an aggregate area of and a population of 1,116 on Isla María Madre as of the census of 2005 along with around 8,000 prisoners. The other islands are uninhabited. The main settlement is ''Puerto Balleto, Islas Marías, Puerto Balleto'', with a population of 602.

Isla María Madre is the largest of the islands, with an area of . It houses the Islas Marías Federal Prison, which was established there in 1905.

Geology

Research supports the hypothesis that the Islas Marias are fragments of continental crust left over from the separation of the Baja California Peninsula from the mainland of Mexico. Rocks found on the islands correspond with rocks found around Cabo San Lucas, as well as Puerto Vallarta.

Fauna

Prison of Isla Maria

The Islas Marías Federal Prison was constructed in 1905. One of its more notable prisoners was the Mexican progressive writer Jose Revueltas who wrote his first book ''Los Muros de Agua'' (''The Walls of Water'', publ.1941) while incarcerated there.

President of Mexico Andrés Manuel López Obrador announced on February 18, 2019, that his administration would close the Islas Marías Federal Prison, replacing it with a new cultural center that will be named for José Revueltas.[''San Francisco Chronicle'', February 19, 2019, p.A-2]
