To avoid the first frost, Navajo herders move their livestock to lower ground when aspen trees drop their leaves. Others watch the stars and the moon to gauge the timing of seasonal movements. But with changing climate in the Southwest, nature’s signs have become less reliable.


For millennia, people have coveted rare goods they could get only through trade with others. The Ancestral Puebloans of the Colorado Plateau were no exception. They traveled great distances to exchange items like local turquoise, hides, and pottery for exotic shells, copper bells, and cacao.


The name is practically as long as the animal itself: the “chisel-toothed kangaroo rat.” It lives in desert landscapes from Oregon and California through Utah and into northwest Arizona.

The high plateau of Cedar Mesa in southern Utah is a stunning bit of scenery and archaeology. Early Puebloan farmers grew crops there and built stunning dwellings inside snug, dry sandstone alcoves. When they departed, they left behind tantalizing traces of their lives.


Sometimes what looks like a white plastic bag snagged in the top of a pine tree is only a plastic bag. Sometimes it’s something else – a bag of bugs, you might say.

When presidents approach the end of a term, an otherwise little-known federal law often hits the headlines. It’s the Antiquities Act, passed by Congress in 1906.

How do we know who lives where? Increasingly, land managers are turning to a fun and educational event to find out: the bioblitz.
