Scientists have found evidence of what could be the earliest known use of fire by humans in North America. A scientist at Northern Arizona University is part of the team that sampled ancient charcoal on the Channel Islands, off the coast of southern California.

The Grand Canyon, Wupatki National Monument and Sunset Crater Volcano are some of the geologic and cultural gems of the National Park Service. This summer, KNAU's Earth Notes series will highlight these, and other special places across the Southwest in honor of the Park Service's 100th anniversary. In the fourth installment of the series, we look at northern Arizona's Pipe Spring National Monument and its rich human history.

To many Colorado Plateau tourists, Pipe Spring National Monument is about as far from civilization as it gets—a 40-acre flyspeck tucked onto the vast Arizona Strip between the North Rim of Grand Canyon and the colorful canyon parks of southern Utah.


Northern Arizona University contributed to a recent study that suggests sexual violence is widespread among college-age athletic men. That was linked to athletes’ attitudes towards women.

New Mexico’s Valles Caldera National Preserve is one of the nation’s newest national parks. It is also a living laboratory.

Flagstaff has long been a training destination for world class athletes. The high altitude makes their bodies produce more red blood cells and absorb more oxygen, which in turn builds their endurance and speed. Canadian exercise physiologist Trent Stellingwerff wants to know what else happens when elite athletes train at 7,000 feet.
