From grizzlies, Dall sheep, and the elusive wolverine to bald eagles and the common ground squirrel, photographer Tom Walker displays birds, mammals, and more from work that spans four decades. This is a Best of collection from a celebrated Alaskan writer and photographer. Captions focus on factual natural history interpretation; for example: An Arctic ground squirrel's body temperature can drop below 32 degrees F without its tissues actually freezing. Hibernating squirrels are the 'coldest mammal alive.' Their heart rates drop from 200 beats-per-minute to 2 bpm with a pulse every 30 seconds.
This new gift book is seasonally organized, revealing the wondrous Alaska landscape and the activities and behavior of a variety of species during spring, summer, autumn, and winter. Park visitors, families, classrooms, and readers of all ages will delight in the range of beautiful images and learn what is happening in Alaska's natural world throughout the year.
