Freelance writer Amy Grisak began her media career carrying gear--and serving as sound recordist and associate producer--for nearly ten years while working on programs for National Geographic Television. Her introduction to Yellowstone National Park was during the filming of "Yellowstone: Realm of the Coyote," where she reveled in the unparalleled wildlife opportunities and fascinating geology.

Grisak eventually transitioned from television to freelance writing, pairing her nature photography with her stories and essays for the Great Falls (Montana) Tribune and other regional and national publications. She is the author of Nature Guide to Glacier and Waterton National Parks and an active member in the Outdoor Writers Association of America.

When she's not writing, Grisak co-hosts Front Range Outdoors, a Great Falls radio program where she discusses the wide range of outdoor recreation throughout Montana.

As soon as the snow recedes in the spring, Amy is on the trails with her two sons or fishing with her husband near their Great Falls' home. She loves exploring the stunning landscape she is blessed to call home. Follow her work at amygrisak.com.
