Today, the West’s amber waves of grass are more often than not a species land managers cringe to see. Cheatgrass, a Eurasian species that most likely arrived on ships a century ago, now runs across millions of acres of the Intermountain West and Colorado Plateau.
The managers of nature-oriented parks, including many on the Colorado Plateau, don’t always know how many visitors to expect, or when peak visiting times will come.

Herbert Ernest Gregory isn’t exactly a household name among Colorado Plateau residents.
