Gila monsters, geysers, and grizzly bears in America's own backyard

Edición de la obra Park scientists

Describes the work of scientists in America's national parks, as they study geysers, grizzly bears, salamanders, cacti, and fireflies. Rare fireflies and red-cheeked salamanders, found nowhere else in the world, are just two of the unique subjects in U.S. national parks. Photographs and text take readers into three parks to discover what scientists are studying and learning.
