Flora & Fauna--Largely a mixed-grass prairie, the park contains 56 different types of grasses, most of which are native species, including green needlegrass and buffalo grass. Wildflowers, including curlycup gumweed and pale purple coneflower, add color, with the best wildflower displays in June and July. What you won't find here are many trees.
Wildlife to watch for includes bison, Rocky Mountain bighorn sheep, pronghorns, and mule deer. Darting in and out of the grass are desert and eastern cottontail rabbits. Prairie dogs thrive here; there's a prairie dog town 5 miles down Sage Creek Rim Road. You might also see a prairie rattlesnake slithering through the grass, plus several nonpoisonous snake species.
