The Tallgrass Prairie Preserve appears as a blanket over mounds of earth. A cream-colored path stands as the only landmark sewn into this quilted sea.  It did appear this way, as a sea. That was until I settled into the grasses and peered at the depth that surrounded me. Each grass was unique. It was not a sea at all. It was a complicated environment teeming with flowers and petals, seeds and sprouts. On certain occasions it is best to stop looking at the blanket as a blanket and to instead view it as a series of knots and patterns.
