Chaco canyon was a a.political/military center

Chaco Canyon is a famous archaeological area in the American Southwest. It is located in the region known as the Four Corners, where the states of Utah, Colorado, Arizona, and New Mexico meet. This region was historically occupied by Ancestral Puebloan people (better known as Anasazi), and is now part of the Chaco Culture National Historical Park.

Chief Massasoit, a Wampanoag, and Squanto, a Patuxet Indian, helped the Pilgrims of Plymouth Bay establish their colony by teaching them skills in cultivating this land and hunting. In return for weapons and tools, these Native Americans provided the colonists with important natural resources, including food.
