[单项选择]Think all of Kansas is flat Think again. The Flint Hills, in the eastern part of the state, fan out over 183 miles from north to south, stretching 30 to 40 miles wide in parts, the land folding into itself, then popping up in gentle bumps, with mounds looming far off on the horizon. Seemingly endless, the landscape offers up isolated images--a wind-whipped cottonwood tree, a rusted cattle pen, a spindly windmill, an abandoned limestone schoolhouse, the metal-gated entrance to a hilltop cemetery.
Proud of the region’s beauty, Kansas has seen to it that 48 miles of its Highway 177, leading through the heart of the hills, are designed the Flint Hills National Scenic Byway. This stretch starts about 50 miles northeast of Wichita and leads north to the Tallgrass Prairie National Preserve, one of the few place left in the United States where a visitor can see the grasses that once covered so much of the American heartland.
