A photograph by Marilyn Friesen of the Flint Hills or Tall Grass Prairie area in central Kansas, USA. The foreground shows a protrusion of the flint deposits that the area is named for. The photo depicts early Spring as noted by the short green grasses.

In March or early April, ranchers will burn the previous year's growth of tall brown grass, resulting in the new green growth seen in the photo. By late September, early October, the grass will be knee-high.

The grass fed the huge herds of Bison that roamed here once. Now herds of cattle graze on it.
