Armstrong has spent hours observing the small, furry creatures, and his photographs show adult marmots perched on rocky outcrops giving their signature alarm whistles, youngsters tumbling and boxing with one another, and in one sequence a mother marmot moving her youngsters to the safety of a rock burrow.
A text suitable for young readers as well as adults describes the marmots' seasonal lifestyle, and an illustration by Juneau artist Katherine Hocker depicts a typical tunnel where a marmot family would spend the winter hibernating.
There's interesting information about the squirrel family, including other ground squirrels, tree squirrels, and flying squirrels; and photos of other animals found on the mountainsides where marmots live.
The book is softbound and 8-1/2"x11" in size. It will be sold in bookstores and other outlets throughout Alaska and the Pacific Northwest.
