Context: Mexico (, modern Nahuatl ), officially the United Mexican States, is a federal republic in the southern half of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost two million square kilometers (over 760,000sqmi), Mexico is the sixth largest country in the Americas by total area and the 13th largest independent nation in the world. With an estimated population of over 120 million, it is the eleventh most populous country and the most populous Spanish-speaking country in the world while being the second most populous country in Latin America. Mexico is a federation comprising 31 states and a federal district that is also its capital and most populous city. Other metropolises include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and Leon., Fajada Butte is a butte in Chaco Culture National Historical Park , in northwest New Mexico . Fajada Butte ( Banded Butte ) rises 135 meters above the canyon floor . Although there is no water source on the butte , there are ruins of small cliff dwellings in the higher regions of the butte . Analysis of fragments of pottery found on Fajada show that these structures were used between the 10th to 13th centuries ( Ford 1993 , p. 474 ) . The remains of a 95 - meter - high , 230 - meter - long ramp are evident on the southwestern face of the butte ( Ford 1993 , p. 478 ) . The magnitude of this building project , without an apparent utilitarian purpose , indicates that Fajada Butte may have had considerable ceremonial importance for the Chacoan people ., New Mexico is a state located in the southwestern region of the United States of America. It was admitted to the union as the 47th state on January 6, 1912. It is usually considered one of the Mountain States. New Mexico is fifth by area, the 36th-most populous, and the sixth-least densely populated of the 50 United States., Chaco Culture National Historical Park is a United States National Historical Park hosting the densest and most exceptional concentration of pueblos in the American Southwest. The park is located in northwestern New Mexico, between Albuquerque and Farmington, in a remote canyon cut by the Chaco Wash. Containing the most sweeping collection of ancient ruins north of Mexico, the park preserves one of the most important pre-Columbian cultural and historical areas in the United States., Pueblos are modern and old communities of Native Americans in the Southwestern United States. The first Spanish explorers of the Southwest used this term to describe the communities housed in apartment structures built of stone, adobe mud, and other local material. These structures were usually multi-storied buildings surrounding an open plaza. The rooms were accessible only through ladders lowered by the inhabitants, thus protecting them from break-ins and unwanted guests. Larger pueblos were occupied by hundreds to thousands of Pueblo people. Several different federally recognized tribes have traditionally resided in pueblos of such design.
Etymology and usage.
The word "pueblo" is the Spanish word for "town" or "village". It comes from the Latin root word "populus" meaning "people"., The Chaco Wash is an arroyo (a periodic stream) cutting through Chaco Canyon, which is located in northwestern New Mexico on the Colorado Plateau. Another arroyo known as Escavada Wash is a tributary that feeds in from the northeast, near the western end of Chaco Canyon. Chaco Wash flows northwest to become the intermittent Chaco River. It is a tributary of the San Juan River., The Western United States, commonly referred to as the American West, the Far West, or simply the West, traditionally refers to the region comprising the westernmost states of the United States. Because European settlement in the U.S. expanded westward after its founding, the meaning of the West has evolved over time. Prior to about 1800, the crest of the Appalachian Mountains was seen as the western frontier., A butte is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller than mesas, plateaus, and table landforms. The word butte comes from a French word meaning "small hill"; its use is prevalent in the Western United States, including the southwest where "mesa" is also used for the larger landform. Because of their distinctive shapes, buttes are frequently landmarks in plains and mountainous areas.
In differentiating mesas and buttes, geographers use the rule of thumb that a mesa has a top that is wider than its height, while a butte has a top that is narrower than its height., Subject: fajada butte, Relation: country, Options: (A) mexico (B) united states (C) united states of america (D) world
