Grasslands National Park

It’s all about the sky here — almost too blue and too vast to be real. Grasslands features one of the last intact ecosystems of its kind — a semi-arid landscape of mixed grasses, sedges and shrubs, whose windswept warm tones contrast with the sky above. That ground cover is shelter or food for several threatened species, including burrowing owls, pronghorns, greater sage-grouse and plains bison — reintroduced here in 2006, after nearly going extinct around the turn of the 20th century.
