The sun was setting farther in the distance than this little Indiana girl had ever seen. Between me and the rugged, mountainous horizon was a scene of variegated green that seemed to be rolling my way. Foothills rose in the faded yellow-green of drying grasses, giving way to stately stripes of blue-green pine. Bright green bursts of cottonwoods shedding their wispy down offset the gray-green of Russian Olive and Silver Sage. And all served as backdrop to the stars of the show, the reintroduced bison lumbering their way across an expansive meadow made lush and vibrant by the late-season runoff.
