Earth from Space: America’s Tuscany
Rolling hills of farmland in the northwest United States are pictured in this image from the Kompsat-2 satellite.
Acquired over Washington state, the south and west areas of the image are in Walla Walla county, while the central-eastern-upper area is Columbia County.
Washington is one of the country’s leading agricultural states. Major crops include apples, raspberries, cherries, lentils, asparagus, hops and grapes. It is also one of the top wine producing states.
The area pictured is part of the Palouse region – an agricultural zone that mainly produces wheat and legumes. The rolling, picturesque landscape has sometimes been compared to Italy’s Tuscany. These fertile hills were formed during the ice ages, with highly productive loess sediment formed by the accumulation of wind-blown silt.
Only about 1% of the original Palouse grasslands still exist, as conversion to agriculture destroyed more than 99%. The remaining grasslands are highly fragmented.
Zooming in, we can see swirling patterns in the vegetation created by ploughs. Roads cut through the shallow valleys and buildings can also be seen.
Touchet River, known for its trout fishing, can been seen in the lower left. The diagonal line running next to the river is a road that connects the town of Prescott to the west to Waitsburg to the east.
This image was acquired by the Korea Aerospace Research Institute’s Kompsat-2 on 13 September 2012 and it is featured on the Earth from Space video programme.
