Imagine, if you will, how the plains and prairies of Midwest America used to appear before the eyes of the beholders, had they been farmers, traders, or frontiers people of any ilk who came upon these lands. This diverse ecosystem, both flora and fauna, stretched out in all directions and covered nearly one-third of North America in a sea of grass.
From new growth in spring through the first frosts of fall, tallgrass prairies grow and proliferate in fertile, wetter areas. Consequently, the amount of rainfall they receive all summer determines their maximum height in September/October. This National Park Service area in the Flint Hills of Kansas is dedicated to the largest intact-tallgrass prairie left in the USA, (a mere 4% of what used to be.)
Although open year-round, visitor high-season generally runs through October 31st. Now would be the best time to see these grasslands at their tallest. Enjoy!
