For those living in the American Southwest, dust is as much a part of the environment as dryness and sunshine. Tiny particles seem to get into everything, including houses, cars, and noses.
While dust can be annoying, scientists believe it plays a vital role in the region’s ecology. It appears to provide essential minerals and chemical compounds to high-mountain ecosystems, just as seafaring salmon bring ocean nutrients high up into freshwater streams.
Electricity-generating wind turbines are a common sight these days. Yet their popularity is limited by the fact that the wind stops blowing from time to time, even on the breezy western plains. But a planned wind farm, and a set of caves, in the interior West may represent a creative solution to this problem.
The Pathfinder Renewable Wind Energy project is the name for a proposed utility-scale facility that would provide Southern California with over two gigawatts of green power. That’s double the amount produced by Hoover Dam, and enough to serve over a million homes.
One of the enduring mysteries of the Colorado Plateau is why the area’s ancient Puebloan population dropped to almost zero in the late 13th century, after peaking at as many as 40,000 people just 30 years earlier.
In the future today’s young people are going to be making important decisions about a host of environmental challenges faced by the southwestern states, from climate change and wildfires to habitat loss and pollution.
For over three decades, a gleaming grid of 400 stainless steel poles has drawn art-world visitors to a place more accustomed to pronghorn and occasional wandering cattle—the high, lonesome desert of western New Mexico’s Catron County.
Commissioned by the Dia Art Foundation of New York, the Lightning Field is the creation of sculptor Walter de Maria, who in the 1970s designed this Earth Art sculpture as an homage to place—and to people’s relationship to it.
For centuries, New Mexico’s Pueblo peoples have relied on the plants and animals of the Río Grande to sustain their lifestyles and traditions. But in recent times the river has been impacted by development, diversion, and flood control. That can make it difficult to maintain some key cultural practices. What is the purpose of a deer dance, for example, if there are no deer?
Not content to sit idly by, three pueblos near Española, in northern New Mexico, have formed an unprecedented alliance to mitigate damage along a dozen miles of river corridor.
Fewer than five percent of the more than 550 U.S. wildlife refuges are located in urban areas. In New Mexico, another is joining the list as the former Price’s Dairy near downtown Albuquerque is slated to become the Middle Rio Grande Wildlife Refuge. At almost 600 acres and only five miles from downtown, it is the largest farm left in a metropolitan area now home to nearly one million people.
This month, as nights grow long, Earth Notes pays homage to the sun and to some of the lesser-known ways it can fuel our lives.
It’s well known that photovoltaic solar panels produce clean, renewable energy. But a new study suggests that they can have an unintended consequence: in some climates, panels mounted on roofs may help keep interiors cool in summer and warm in winter.
