Havasupai in the context of Atchison, Topeka and Santa Fe Railway

The Havasupai Indian Reservation is a Native American reservation for the Havasupai people, bordering Grand Canyon National Park, in Coconino County in Arizona, United States. It is considered one of America's most remote Indian reservations. The reservation is governed by a seven-member tribal council, led by a chairman who is elected from among the members of the council. The capital of the reservation is Supai, situated at the bottom of Cataract Canyon (also known as Havasu Canyon), one of the tributary canyons of the Grand Canyon. Havasupai is a combination of the words Havasu (meaning "blue-green water") and pai (meaning "people"), thus meaning "people of the blue-green waters".

Squatting is a versatile posture where the weight of the body is on the feet but the knees and hips are bent. In contrast, sitting involves supporting the weight of the body on the ischial tuberosities of the pelvis, with the lower buttocks in contact with the ground or a horizontal object. The angle between the legs when squatting can vary from zero to widely splayed out, flexibility permitting. Another variable may be the degree of forward tilt of the upper body from the hips. Squatting may be either full or partial.

Crouching is usually considered to be synonymous with squatting. It is common to squat with one leg and kneel with the other leg. One or both heels may be up when squatting. Young children often instinctively squat. Among Chinese, Southeast Asian and Eastern European adults, squatting often takes the place of sitting or standing.

Coconino County is a county in the North-Central part of the U.S. state of Arizona. Its population was 145,101 at the 2020 census. The county seat is Flagstaff. The county takes its name from Cohonino, a name applied to the Havasupai people. It is the second-largest county by area in the contiguous United States, behind San Bernardino County, California. It has 18,661 sq mi (48,332 km), or 16.4% of Arizona's total area, and is larger than the nine smallest states in the U.S.

Coconino County comprises the Flagstaff metropolitan statistical area, Grand Canyon National Park, the federally recognized Havasupai Nation, and parts of the federally recognized Navajo, Hualapai, and Hopi nations. As a result, its relatively large Native American population makes up nearly 30% of the county's total population; it is mostly Navajo, with smaller numbers of other tribes.

Havasupai–Hualapai (Havasupai–Walapai) is a Native American language spoken by the Hualapai and Havasupai peoples of northwestern Arizona. Havasupai–Hualapai belongs to the Pai branch of the Yuman–Cochimí language family, together with its close relative Yavapai and with Paipai, a language spoken in northern Baja California. There are two main dialects of this language: the Havasupai dialect is spoken in the bottom of the Grand Canyon, while the Hualapai dialect is spoken along the southern rim. As of 2010, there were approximately 1500 speakers of Havasupai-Hualapai. UNESCO classifies the Havasupai dialect as endangered and the Hualapai dialect as vulnerable. There are efforts at preserving both dialects through bilingual education programs.
