When bears raid campsites, it might be because of a relationship that developed thousands of years ago between humans and carnivores. That's what an archaeologist at Northern Arizona University believes. Chrissina Burke is looking at ancient bison kill sites to prove that wild animals have been conditioned to see humans as food providers. 

Burke says, "The research focuses is really focused on how do humans impact animals on the landscape. So, what I've been looking at in that context is how carnivores came in, saw, and said, 'Oh hey look! A smorgasbord. Free food!"

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 fifth installment of the series, we look at Hubbell Trading Post in Ganado, Ariz., which served as a community hub since it opened in the 1870s.

The arid Southwest is ideal for preserving plant and animal remains. It's a living laboratory for scientists. At the Ancient DNA Lab at Northern Arizona University, wildlife geneticist Faith Walker is using tiny pieces of mummified biological material to learn more about life on Earth thousands of years ago.

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.

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