Humor is a form of commentary that often reveals serious truths. Cartoonists combine artistic talents with razor-sharp wits to shine light on political and social issues. In most cases, those artists are external observers. In the National Park Service (NPS), employees in the 1960s to 1980s drew cartoons, published in official newsletters, that provide unique insights into NPS organizational culture, working conditions, and employees' concerns—many of which still exist today.
Volcanologist Erika Rader's first thought about visual near-infrared spectroscopy equipment was, "I don't understand this and therefore I don't believe it works, but planetary scientists use it a lot so maybe I should give it a think." Soon after, she wanted to share the technology with others.
Pikas live in the expansive lava flows of Craters of the Moon National Monument and Preserve—an atypical habitat in a harsh environment. Here we have a spectacular opportunity to learn more about how this species may respond to climate change over time.
Craters of the Moon hosts at least nine species of bats year-round with several others passing through the area.

Wildlife biologists at Craters of the Moon National Monument and Preserve have a unique opportunity to understand pronghorn migration through the park. Pronghorns are one of the West’s iconic animals and have one of the longest land migrations in North America. A narrow migration corridor in Craters of the Moon allows for the use of trail cameras to capture pronghorns during their annual movements. The data from this study supports management decisions at the park.
The Cenozoic Era (66 million years ago [MYA] through today) is the "Age of Mammals." North America’s characteristic landscapes began to develop during the Cenozoic. Birds and mammals rose in prominence after the extinction of giant reptiles. Common Cenozoic fossils include cat-like carnivores and early horses, as well as ice age woolly mammoths.
