A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. The term generally refers to rock engravings of ancient origin, often associated with prehistoric peoples. The oldest petroglyphs in the world are deemed to be those at Murujuga in Western Australia, which are 40,000–50,000 years old. Some petroglyphs are classified as protected monuments and some have been added to the list of UNESCO's World Heritage Sites, or such status has been applied for.

Ulama (Spanish pronunciation: [uˈlama]) is a ball game played in Mexico, currently experiencing a revival from its home in a few communities in the state of Sinaloa. As a descendant of the Aztec version of the Mesoamerican ballgame, the game is regarded as one of the oldest continuously played sports in the world and as the oldest known game using a rubber ball.

Chihuahua, officially the Free and Sovereign State of Chihuahua, is one of the 31 states which, along with Mexico City, are the 32 federal entities of Mexico. It is located in the northwestern part of Mexico and is bordered by the states of Sonora to the west, Sinaloa to the southwest, Durango to the south, and Coahuila to the east. To the north and northeast, it shares an extensive border with the U.S. adjacent to the U.S. states of New Mexico and Texas. The state was named after its capital city, Chihuahua City; the largest city is Ciudad Juárez. In 1864 the city of Chihuahua was declared capital of Mexico by Benito Juárez during the Reform War and French intervention until 1867. The city of Parral was the largest producer of silver in the world in 1640. During the Mexican War of Independence, Miguel Hidalgo was executed on July 30, 1811, in Chihuahua city.

Although Chihuahua is primarily identified with its namesake, the Chihuahuan Desert, it has more forests than any other state in Mexico, aside from Durango. Due to its varied climate, the state has a large variety of fauna and flora. The state is mostly characterized by rugged mountainous terrain and wide river valleys. The Sierra Madre Occidental mountain range, part of the continental spine that also includes the Rocky Mountains, dominates the state's terrain, and is home to the state's greatest attraction, Las Barrancas del Cobre, or Copper Canyon, a canyon system larger and deeper than the Grand Canyon. The state also has the largest crystal cave in Mexico known as the Naica cave discovered in 2001. Chihuahua is also home to the archaeological site of Paquimé in Casas Grandes that was created by the people of the Mogollon culture of Northern Mexico and is recognized as an UNESCO World Heritage site. Chihuahua is the largest state in Mexico by area, with an area of 247,455 square kilometres (95,543 sq mi), it is slightly larger than the United Kingdom, and slightly smaller than Wyoming, the tenth largest US state by area. The state is consequently known under the nickname El Estado Grande ('The Great State' or 'The Big State').

The Mexican Dirty War (Spanish: Guerra sucia) was the Mexican theater of the Cold War, an internal conflict from the 1960s to the 1980s between the Mexican Institutional Revolutionary Party (PRI)-ruled government under the presidencies of Gustavo Díaz Ordaz, Luis Echeverría, and José López Portillo, which were backed by the U.S. government, and left-wing student and guerrilla groups. During the war, government forces carried out disappearances (estimated at 1,200), systematic torture, and "probable extrajudicial executions".

In the 1960s and 1970s, Mexico was persuaded to be part of both Operation Intercept and Operation Condor, developed between 1975 and 1978, with the pretext to fight against the cultivation of opium and marijuana in the "Golden Triangle", particularly in Sinaloa. The operation, commanded by General José Hernández Toledo, was a flop with no major drug-lord captures, but many abuses and acts of repression were committed.

Northern Mexico (Spanish: el Norte de México, pronounced [el ˈnoɾte ðe ˈmexiko] ), commonly referred as The North (Spanish: El Norte), is an informal term for the northern cultural and geographical area in Mexico. Depending on the source, it contains some or all of the states of Baja California, Baja California Sur, Chihuahua, Coahuila, Durango, Nuevo León, Sinaloa, Sonora and Tamaulipas.

There is no specific border that separates the northern states from the southern states in Mexico. For some authors, only states that have a border with the United States are considered as northern Mexico, i.e. Baja California, Chihuahua, Coahuila, Nuevo León, Sonora and Tamaulipas. Others also include Durango, Sinaloa and Baja California Sur. Other people consider that the north starts above the Tropic of Cancer, but this description would include some parts of Zacatecas and San Luis Potosí that are not considered northern states.
