English: A thick, rippling plume of dust runs north-east to south-west through the centre of this image. Dust stretches as far south as the cities of Pasco and Kennewick, which sit on opposite banks of the Columbia River. In the north, the dust seems to rise primarily from the pale golden squares of fields farmed using dry-land agriculture, a common practice in arid eastern Washington. The dry-land fields are larger and less colourful than the bright green and gold fields of irrigated agriculture near the Columbia and Snake Rivers in the centre of the image.
