A failed copper mine led to one of the Grand Canyon’s first hotel. Then the railroad arrived — and the hotel disappeared. But parts of it are still standing today.

Every hunting season since 1998, the Arizona Game and Fish Department has asked hunters to bring them elk and deer heads to test for chronic wasting disease.

More than eight decades ago, pioneering Museum of Northern Arizona geologist Major L.F. Brady made a surprising find in sedimentary rocks high up on the east flank of Mt. Elden.

A tiny cactus that survives intense wildfire could offer clues about the resilience of ecosystems on the Colorado Plateau.

The spiral pattern in a sunflower’s seeds isn’t random. It follows a mathematical sequence that appears throughout the natural world.

Monsoon rains bring a torrent of colors to the Colorado Plateau. Yellow sunflowers emerge beside purple asters, blush-colored penstemons, and mauve lupine.

On the evening of October 9, 1946, members of the Kaibab Trail crew at the Grand Canyon National Park were watching the sky during a meteor shower caused by the trail of Comet Giacobini-Zinner.

New research shows a small change in where homes are built could make a big difference for wildlife like elk, mule deer and pronghorn.
