It is still possible to discern the Cornbelt. The peak of green for grasslands of the Northern Great Plains is reached in July. Water lowers the vegetation index so dramatically that lush marsh vegetation is muted. Standing water in the Everglades and other marshes make the southern tip of Florida appear to have little vegetation. In August, high mountain forests of the southwest flourish.
Snow cover is minimal and grasses and shrubs are lush.
The Cornbelt is at the peak of green. In September, some agricultural crops of the Cornbelt are harvested, leaving large areas with lower indications of vegetation. October brings seasonal change. Corn and soybeans have matured and ceased growing. Fall colors begin as deciduous trees lose their leaves.
