Friends Groups and Cooperating Associations
The Glacier National Park Fund supports the preservation of the outstanding natural beauty and cultural heritage of Glacier National Park for the use and enjoyment of present and future generations by fostering public awareness and encouraging private philanthropy.
The Glacier Institute offers exceptional field and science-based educational adventures to people of all ages in the Crown of the Continent, which is the only ecosystem in the lower forty eight states where all indigenous predator and prey species are naturally occurring, including grizzly bears and gray wolves. It is a place rich in biological diversity, Native American heritage and unique geological features.
The Glacier Association operates non-profit bookstores to support Glacier National Park interpretation and education activities and programs. It also serves as an official park partner specializing in educational and interpretive materials. The Glacier Association does not actively fundraise, but provides Aid to Agency funding to Glacier National Park in three areas: education, interpretation, and research. Aid supports the printing of free publications developed by the park, Native America Speaks performer stipends (ticket sales go toward initiative), and the park’s Museum.

Add Stars Above, Earth Below, a Guide to Astronomy in the National Parks to your library and you'll not only gain a better appreciation of the dark skies over national parks, but you'll also be better informed on the stars twinkling at you.
One of the most direct books I've read on avoiding bears in the backcountry is Dave Smith's Backcountry Bear Basics, which recently arrived in its second edition.
