Biohazard and Pathogen Disinfection in Teec Nos Pos, AZ

Teec Nos Pos is a census-designated place (CDP) on the Navajo Nation in Apache County, in the Four Corners region of northeastern Arizona.

Its Navajo name, T'iis Názbąs, means "cottonwoods in a circle," after the grove of cottonwood trees at the original settlement.

The U.S. Geological Survey officially recorded the community in 1915 as Tisnasbas, when it stood several miles south of its present location; it was renamed Teec Nos Pas in 1960 and Teec Nos Pos in 1983.

The population later moved north to the junction of U.S. Route 160 and U.S. Route 64, and Teec Nos Pos is the western terminus of U.S. Route 64.

A trading post established at Teec Nos Pos in 1897 remains in operation, one of the few historic Navajo trading posts still doing business.

The community is the center for Navajo weaving of the distinctive Teec Nos Pos rug patterns.

In the 1930s, the Indian Irrigation Service constructed two concrete diversion dams on nearby T'iisnazbas Creek, irrigating approximately 400 acres of Navajo farmland.

The 2020 census counted 507 residents in Teec Nos Pos, down from 730 at the 2010 census and 799 at the 2000 census.

At the 2000 census, Teec Nos Pos had 227 households, and the average household size was 3.52 people.

Teec Nos Pos is the closest settlement of any size to the Four Corners Monument, about 7 miles to the northeast, where Arizona, Utah, Colorado, and New Mexico meet.
