Within the prairies were many landscapes…. There were hanging bogs with strange calcareous flora, “walled” lakes with cobble beaches and orderly shorelines of glacial boulders, waves of flowers advancing with each stage of the growing season, and myriad patterns and textures of grasses that varied moment by moment with sun and wind and the cloud shadows that drove across the land. There were a thousand worlds within this one world of grass. Some men sensed that at once; others never did.
