The Arctic Circle region of northern Sweden is the home of the Saami, or Lapp people. It is the largest area in the world (and one of the last) with an ancestral way of life based on the seasonal movement of livestock. Every summer, the Saami lead their huge herds of reindeer towards the mountains through a natural landscape hitherto preserved, but now threatened by the advent of motor vehicles. Historical and ongoing geological processes are reflected by the glacial moraines and changing watercourses. The lakes and landscapes of the Swedish national park Padjelanta are visible in the image. The spectral channels of the Landsat satellite were combined to yield information primarily from the infrared part of the spectrum. This allows vegetation and rocks to be more easily differentiated. Snow and ice appear turquoise and water surfaces black in such images.

The image was taken on 25 June 1992 by the satellite Landsat-7 / ETM+ and has a resolution of 30 metres. It covers an area of 80 by 160 kilometres.
