Chaco Canyon National Historical Park is noted for amazing structures called Great Houses -- massive buildings constructed by the Ancestral Puebloans, who inhabited the nearly treeless high desert of northwestern New Mexico a thousand years ago. Besides local stone and earth, nearly a quarter million trees were harvested for beams in the buildings.

This year marks the centennial of the Migratory Bird Treaty, an agreement signed in 1916 to help conserve, protect, and manage migrating birds and their habitats throughout the U.S. and Canada. The 100th anniversary is a reminder that such birds play vital ecological roles. They are also good indicators of the health of our environment.


Each year in spring and early summer, families across the Navajo and Hopi Nations gather to plant crops on their land. This year preparations were more thorough than usual for a group of Native students who took part in a seven-month organic agriculture training program at Tolani Lake Enterprises near Leupp, Arizona.
