About 500 people packed the The Gryphon Theatre November 30th to see Wyoming Migration Initiative photography fellow Joe Riis present highlights from the last ten years of his work photographing elk, mule deer, and pronghorn migrations of the Greater Yellowstone Ecosystem. WMI research associate Hall Sawyer introduced the talk, while Wild Migrations atlas text editor Emilene Ostlind read an essay about how she and Joe documented the Path of the Pronghorn starting in 2008. Ostlind’s essay appears in Riis’ new YELLOWSTONE MIGRATIONS book from publisher Braided River. You can order the book directly here.
