\"\"<\/a>
Blurred Horizon by Amy Hoagland.<\/sup><\/em><\/figcaption><\/figure>\n\n\n\n

In practically every depiction of the Flint Hills, it\u2019s there. The line. Sometimes it\u2019s as sharp as a blade. A dark, earthen-colored slash slicing across the canvas. Other times, it bleeds. Colors mingling, pigments loosened by water or blurred by distance.<\/p>\n\n\n\n

In either case, the artist has divided the world the way most of us do \u2014 into two halves: earth and sky, land and air, matter and vapor. Opposing realms separated by that long, unbending, unbroken line<\/em>.<\/p>\n\n\n\n

Indeed, the word \u201chorizon\u201d comes from the Greek verb hor\u00edz<\/em><\/a>\u014d<\/em>, which means \u201cto divide.\u201d Hor\u00edz<\/a>\u014d, in turn, derives from horos<\/em>, an old word for \u201cboundary.\u201d The horizon cleaves the physical world in two.<\/p>\n\n\n\n

And yet the horizon is an illusion. The sky meets the ground not out there<\/em> but all around us, all the time. It may be a fact of our visual field, but the line<\/em> is little more than a mirage, conjured by the curvature of the Earth. Like the end of a rainbow, it recedes infinitely before us.<\/p>\n\n\n\n

The line deceives us in another way. It obscures the deep, intrinsic land-sky connections that gave birth to the Flint Hills and that remain integral to its ability to sustain life.<\/p>\n\n\n\n

We learn at an early age that plants rely on rain and sunlight to grow and that most inhale carbon dioxide and exhale oxygen. Increasingly, we also understand that, in the tallgrass prairie, much of the digested carbon is sequestered, stored in the grasses\u2019 deep, matted pillars of roots and the surrounding soil.<\/p>\n\n\n\n

But this is just the barest of sketches of what is a dizzying array of dynamic relationships. If we had X-ray vision, we would see that the ground \u2014 and all the life that grows and feasts upon and within it \u2014 is not a hard line at all, but a loose and fuzzy interface, permeable, like the wall of a cell, perpetually mediating the meeting of Earth and sky.<\/p>\n\n\n\n

Perhaps a better way to view the Flint Hills, then, is not in wide, horizontal panorama but in cross section, a tall, narrow slice of stone-soil-prairie-troposphere, a 40,000-foot tableau stretching from deep below the surface to the parapets of the tallest cumulonimbus.<\/p>\n\n\n\n

Start at the top, miles above where passerines forage among the prairie grasses. Here, invisible rivers flow northward from Mexico\u2019s Yucatan Peninsula and collide with the wrung-out westerly winds tumbling over the Rocky Mountains, forming a climate that is prone to extremes. <\/p>\n\n\n\n

Although scientists have had a handle on the basics of Earth\u2019s hydrological cycle since the 1930s, it was only in the 1990s that researchers discovered that water traveled through the atmosphere in much the same way \u2014 and in much the same volumes \u2014 as it did on land: in narrow, established channels that could be mapped and measured. Atmospheric rivers like the kind that snake their way thousands of feet above the Great Plains transport water in the form of vapor from the tropics toward the frigid poles. They can be hundreds of miles wide and deeper than fifty Mississippi Rivers.<\/p>\n\n\n\n

All that water vapor eventually coalesces and falls to the ground in the form of rain, snow or hail. But the pattern is highly variable. Because deep-rooted prairie grasses do better than most tree species in the face of such variability, they have an advantage in Kansas\u2019 extreme climate. So while we want to say, \u201cThe Flint Hills are a place of billowing grasses and unpredictable weather,\u201d it\u2019s more accurate to say, \u201cThe Flint Hills are a place of billowing grasses because <\/em>of the unpredictable weather.\u201d<\/p>\n\n\n\n

Historically, this atmospheric instability also played a role in the maintenance of the prairie. The collisions happening miles above ground generate electrical imbalances between the ground and the atmosphere, which in turn produce lightning. Without frequent lightning strikes to set the prairies ablaze, the ecosystem may never have gotten established.<\/p>\n\n\n\n

The drama of a Kansas storm, then, is both a mirror and an augur of the drama that unfolds across the landscape during a prairie fire: jagged lines of fire spiderwebbing across both land and sky, connected at the point at which the lightning touches the ground.  <\/p>\n\n\n\n

If what happens in the uppermost reaches of the troposphere shapes the prairie through colliding masses of electrically charged air and water vapor, the conditions closest to the surface \u2014 what we experience most viscerally as \u201cweather\u201d \u2014 is equally important to its ecology, and not just in terms of sunlight or rain. We may not think of wind as an ecological force, but the Flint Hills are home to more than 70 different grasses, and every one of them is pollinated not by buzzing, hopping, humming insects but by the breeze.<\/p>\n\n\n\n

Prairie grasses produce pollen inside of tiny yellow, red or tawny-colored flowers called anthers. The wind sweeps this pollen up into the atmosphere, where it can sail for miles before falling earthward, where, with luck, it will find a feathery, female stigma to pollinate. Like the wind itself, this process is largely imperceptible to humans, but it\u2019s vital to the basic health of the prairie. If we could flip a switch and shut off the wind \u2014 as no shortage of Kansans have likely dreamt of doing \u2014 the prairie would wither to dust. <\/p>\n\n\n\n

At this point, we\u2019ve reached the ground, the line<\/em>, where the sky surely, obviously, ends in a hard stop. Or does it? After all, what is<\/em> the ground? Rock, soil, decaying plant matter. But also: water, oxygen, carbon dioxide. Generally speaking, the \u201cground\u201d is 25 percent water and 25 percent air, which is another way of saying that any square meter of ground is about 50 percent sky.<\/p>\n\n\n\n

The ground beneath our feet might begin to feel even more unstable if we were realize that most of the microorganisms that reside in prairie soils are aquatic, living out their lives in microscopic droplets of water. That bears repeating: A significant amount of the soil\u2019s microfauna \u2014 the tiny beasts that chomp and slurp their way through the underworld \u2014 are not land animals but water creatures<\/em>. They swim about, hoovering nutrients out of the water and preying on other, sometimes parasitic microorganisms. When the soil dries out, these microscopic habitats disappear, and some of the animals die. Others shrivel up and encase themselves in protective chrysalises, in which they lie dormant until the sky opens up and douses the land once again. If the human eye could perceive it, then, we would see a cycle in which the giant rivers overhead flow into a trillion tiny reservoirs underground.<\/p>\n\n\n\n

Perhaps most astonishing is the fact that these land-weather interactions are reciprocal. The amount of moisture in soil and vegetation is not only the result of, but also a cause<\/em> of atmospheric patterns. As water vapor is released from the ground \u2014 through evaporation and transpiration \u2014 the additional moisture can drive changes in local temperatures, cloud formation, and eventually precipitation, resulting in a positive feedback loop. As the sky gives birth to the prairies, so the prairies give birth to their otherworldly skies.<\/p>\n\n\n\n

We can\u2019t descend any further. The only thing left to do is to scrape away the soil. Expose the bedrock, a layer cake of limestone and shale, some strata of which are 70 feet thick. And what is limestone besides the remnant of a former climate? A living record of when the Earth\u2019s atmosphere was far warmer and wetter, when what today we call Kansas was little more than the sediment at the bottom of a shallow sea?<\/p>\n\n\n\n

The author and naturalist Robert MacFarlane writes that \u201climestone can be seen as merely one phase in a dynamic earth cycle, whereby mineral becomes animal becomes rock.\u201d Wait long enough and that rock will \u201ceventually supply the calcium carbonate out of which new organisms will build their bodies, thereby re-nourishing the same cycle into being again.\u201d<\/p>\n\n\n\n

MacFarlane\u2019s observation reveals the true value of a vertical orientation. Viewing the Flint Hills in cross section not only helps us understand the invisible processes that sustain the prairie ecosystem \u2014 it also connects us to other places, other times. What we see when we look at the Flint Hills is a landscape made and remade through forces that are global in nature and that stretch back to a time beyond any human accounting.<\/p>\n\n\n\n

There is beauty in a horizon. For many, it represents possibility, a future not yet realized. But the line<\/em> is also a dangerous fiction, obscuring the interconnectedness of a world not easily sifted into binaries. When I think about the line now, I think about all the other boundaries we erect that seem solid but in reality are porous and that, if looked at hard enough, might dissolve entirely. \ud83c\udf3e<\/p>\n","protected":false},"excerpt":{"rendered":"
